我正在创建设计器图面并将控件加载到运行时。在反序列化/将控件加载到运行时时出现问题。

我尝试过的所有方法似乎都存在某种类型的问题。

例如，面临问题：

控件仍受设计时限制
• 并非所有属性都与所有属性（即嵌套属性）反序列化。
• 似乎确实遵循了控件关联，即面板中的按钮不再存在于面板中，即使该属性在加载后仍是父级。

我已经在git上创建了一个示例项目：Surface Designer Test

有主要的代码片段：

从设计开始的序列化

private void LoadRuntime(int type)
{
    var controls = surface.ComponentContainer.Components;
    SerializationStore data = (SerializationStore)surface.
        _designerSerializationService.Serialize(controls);
    MemoryStream ms = new MemoryStream();
    data.Save(ms);
    SaveData.Data = ms.ToArray();
    SaveData.LoadType = type;
    new RuntimeForm().Show();
}

public object Serialize(System.Collections.ICollection objects)
{
    ComponentSerializationService componentSerializationService = 
        _serviceProvider.GetService(typeof(ComponentSerializationService)) as 
        ComponentSerializationService;
    SerializationStore returnObject = null;
    using (SerializationStore serializationStore = 
        componentSerializationService.CreateStore())
    {
        foreach (object obj in objects)
        {
            if (obj is Control control)
            {
                componentSerializationService.SerializeAbsolute(serializationStore, obj);
            }
            returnObject = serializationStore;
        }
    }
    return returnObject;
}

运行时反序列化

这里是尝试反射：

MemoryStream ms = new MemoryStream(SaveData.Data);
Designer d = new Designer();
var controls = d._designerSerializationService.Deserialize(ms);

ms.Close();
if (SaveData.LoadType == 1)
{
    foreach (Control cont in controls)
    {
        var ts = Assembly.Load(cont.GetType().Assembly.FullName);
        var o = ts.GetType(cont.GetType().FullName);
        Control controlform = (Control)Activator.CreateInstance(o);
        PropertyInfo[] controlProperties = cont.GetType().GetProperties();
        foreach (PropertyInfo propInfo in controlProperties)
        {
            if (propInfo.CanWrite)
            {
                if (propInfo.Name != "Site" && propInfo.Name != WindowTarget")
                {
                    try
                    {
                        var obj = propInfo.GetValue(cont, null);
                        propInfo.SetValue(controlform, obj, null);
                    }
                    catch { }
                }
                else { }
            }
        }
        Controls.Add(controlform);
    }
}

这里尝试直接加载控件（仍然与设计时绑定：]
MemoryStream ms = new MemoryStream(SaveData.Data);
Designer d = new Designer();
var controls = d._designerSerializationService.Deserialize(ms);
foreach (Control cont in controls)
    Controls.Add(cont);

[我觉得我缺少System.ComponentModel.Design框架中的概念。我也不认为有必要为每个控件编写自定义序列化程序，因为可以肯定的是，Visual Studio能够在System.ComponentModel.Design中更改它们的所有属性后，将它们的所有属性序列化，并在运行时将其加载回该程序。
在设计时和运行时之间完成此序列化的正确方法是什么？

Answer 1

这是我从设计图面生成代码的方式：

PropertyGrid

您可以像这样创建设计图面：
string GenerateCSFromDesigner(DesignSurface designSurface)
{
    CodeTypeDeclaration type;
    var host = (IDesignerHost)designSurface.GetService(typeof(IDesignerHost));
    var root = host.RootComponent;
    var manager = new DesignerSerializationManager(host);
    using (manager.CreateSession())
    {
        var serializer = (TypeCodeDomSerializer)manager.GetSerializer(root.GetType(),
            typeof(TypeCodeDomSerializer));
        type = serializer.Serialize(manager, root, host.Container.Components);
        type.IsPartial = true;
        type.Members.OfType<CodeConstructor>()
            .FirstOrDefault().Attributes = MemberAttributes.Public;
    }
    var builder = new StringBuilder();
    CodeGeneratorOptions option = new CodeGeneratorOptions();
    option.BracingStyle = "C";
    option.BlankLinesBetweenMembers = false;
    using (var writer = new StringWriter(builder, CultureInfo.InvariantCulture))
    {
        using (var codeDomProvider = new CSharpCodeProvider())
        {
            codeDomProvider.GenerateCodeFromType(type, writer, option);
        }
        return builder.ToString();
    }
}

因此，您将看到如下形式：
DesignSurface designSurface;
private void Form1_Load(object sender, EventArgs e)
{
    designSurface = new DesignSurface(typeof(Form));
    var host = (IDesignerHost)designSurface.GetService(typeof(IDesignerHost));
    var root = (Form)host.RootComponent;
    TypeDescriptor.GetProperties(root)["Name"].SetValue(root, "Form1");
    root.Text = "Form1";

    var button1 = (Button)host.CreateComponent(typeof(Button), "button1");
    button1.Text = "button1";
    button1.Location = new Point(8, 8);
    root.Controls.Add(button1);

    var timer1 = (Timer)host.CreateComponent(typeof(Timer), "timer1");
    timer1.Interval = 2000;
    var view = (Control)designSurface.View;
    view.Dock = DockStyle.Fill;
    view.BackColor = Color.White;
    this.Controls.Add(view);
}
这是生成的代码：

然后运行它：
public partial class Form1 : System.Windows.Forms.Form
{
    private System.Windows.Forms.Button button1;
    private System.Windows.Forms.Timer timer1;
    private System.ComponentModel.IContainer components;
    public Form1()
    {
        this.InitializeComponent();
    }
    private void InitializeComponent()
    {
        this.components = new System.ComponentModel.Container();
        this.button1 = new System.Windows.Forms.Button();
        this.timer1 = new System.Windows.Forms.Timer(this.components);
        this.SuspendLayout();
        // 
        // button1
        // 
        this.button1.Location = new System.Drawing.Point(8, 8);
        this.button1.Name = "button1";
        this.button1.Size = new System.Drawing.Size(75, 23);
        this.button1.TabIndex = 0;
        this.button1.Text = "button1";
        // 
        // timer1
        // 
        this.timer1.Interval = 2000;
        // 
        // Form1
        // 
        this.ClientSize = new System.Drawing.Size(284, 261);
        this.Controls.Add(this.button1);
        this.Name = "Form1";
        this.Text = "Form1";
        this.ResumeLayout(false);
    }
}

例如：
void Run(string code, string formName)
{
    var csc = new CSharpCodeProvider();
    var parameters = new CompilerParameters(new[] {
    "mscorlib.dll",
    "System.Windows.Forms.dll",
    "System.dll",
    "System.Drawing.dll",
    "System.Core.dll",
    "Microsoft.CSharp.dll"});
    parameters.GenerateExecutable = true;
    code = $@"
        {code}
        public class Program
        {{
            [System.STAThread]
            static void Main()
            {{
                System.Windows.Forms.Application.EnableVisualStyles();
                System.Windows.Forms.Application.SetCompatibleTextRenderingDefault(false);
                System.Windows.Forms.Application.Run(new {formName}());
            }}
        }}";
    var results = csc.CompileAssemblyFromSource(parameters, code);
    if (!results.Errors.HasErrors)
    {
        System.Diagnostics.Process.Start(results.CompiledAssembly.CodeBase);
    }
    else
    {
        var errors = string.Join(Environment.NewLine,
            results.Errors.Cast<CompilerError>().Select(x => x.ErrorText));
        MessageBox.Show(errors);
    }
}

哪个显示：
Run(GenerateCSFromDesigner(designSurface), "Form1");
