CodeDom编译器在访问temp中的dll时遇到问题

Question

Public Function GenerateScript(code As String) As IScript
    Using provider As New VBCodeProvider()
        Dim parameters As New CompilerParameters()
        parameters.GenerateInMemory = True
        parameters.ReferencedAssemblies.Add(Assembly.GetExecutingAssembly().Location)
        Dim interfaceNamespace As String = GetType(IScript).Namespace
        Dim codeArray() As String = New String() {"Imports " & interfaceNamespace & Environment.NewLine & code}
        Dim results As CompilerResults = provider.CompileAssemblyFromSource(parameters, codeArray)
        Return CType(results.CompiledAssembly.CreateInstance("Script"), IScript)
    End Using
End Function

我正在使用上面的代码来运行可能随时间变化的字符串。但是当我运行它时，我收到此错误：

System.IO.FileNotFoundException: 'Could not load file or assembly 'file:///C:\Users\zjf\AppData\Local\Temp\ykujgxkp.dll' or one of its dependencies. The system cannot find the file specified.'

我不知道如何解决这个问题。有人可以帮帮我吗？

谢谢！

您错过了必须在应用程序中实现dll文件的部分，请尝试将其添加到您的代码中：

Parameters.EmbeddedResources.Add("C:\Users\zjf\AppData\Local\Temp\ykujgxkp.dll")
Parameters.ReferencedAssemblies.AddRange(New String() {"System.dll", "System.Drawing.dll", "System.Windows.Forms.dll", "System.Management.dll", "C:\Users\zjf\AppData\Local\Temp\ykujgxkp.dll"})

所以你的最终代码应该是这样的：

Public Function GenerateScript(code As String) As IScript
    Using provider As New VBCodeProvider()
        Dim parameters As New CompilerParameters()
        parameters.GenerateInMemory = True
        Parameters.EmbeddedResources.Add("C:\Users\zjf\AppData\Local\Temp\ykujgxkp.dll")
        Parameters.ReferencedAssemblies.AddRange(New String() {"System.dll", "System.Drawing.dll", "System.Windows.Forms.dll", "System.Management.dll", "C:\Users\zjf\AppData\Local\Temp\ykujgxkp.dll"})
        Dim interfaceNamespace As String = GetType(IScript).Namespace
        Dim codeArray() As String = New String() {"Imports " & interfaceNamespace & Environment.NewLine & code}
        Dim results As CompilerResults = provider.CompileAssemblyFromSource(parameters, codeArray)
        Return CType(results.CompiledAssembly.CreateInstance("Script"), IScript)
    End Using
End Function
