当将数据条修改为实心填充时,如何阻止其他条件格式消失?

问题描述 投票:0回答:1

EPPlus不支持extLst事物,而使用实心填充来进行databars条件格式是必需的。它们本身是渐变的,没有修改。

我编写了此代码,以直接修改工作表的xml(这是从工作表XML中获取数据栏,然后添加所需的extLst节点:]

public static Random Rnd = new Random();

public static string GenerateXlsId()
{
    //{29BD882A-B741-482B-9067-72CC5D939236}

    string id = string.Empty;

    for (int i = 0; i < 32; i++)
        if (Rnd.NextDouble() < 0.5)
            id += Rnd.Next(0, 10);
        else
            id += (char)Rnd.Next(65, 91);

    id = id.Insert(8, "-");
    id = id.Insert(13, "-");
    id = id.Insert(18, "-");
    id = id.Insert(23, "-");

    return id;
}

public static void FixDatabarsAtWorksheet(OfficeOpenXml.ExcelWorksheet eworksheet)
{
    System.Xml.XmlNodeList databars = eworksheet.WorksheetXml.GetElementsByTagName("dataBar");

    if (databars.Count > 0)
    {
        string conditional_formattings_str = string.Empty;

        for (int i = 0; i < databars.Count; i++)
        {
            string temp_databar_id = GenerateXlsId();

            databars[i].ParentNode.InnerXml += @"<extLst>
        <ext uri=""{B025F937-C7B1-47D3-B67F-A62EFF666E3E}"" xmlns:x14=""http://schemas.microsoft.com/office/spreadsheetml/2009/9/main"">
            <x14:id>{" + temp_databar_id + @"}</x14:id>
        </ext>
    </extLst>";
            //--

            string temp_sqref = databars[i].ParentNode.ParentNode.Attributes["sqref"].Value;
            string left_type = string.Empty;
            string left_val = string.Empty;
            string right_type = string.Empty;
            string right_val = string.Empty;
            string color = string.Empty;
            Color databar_fill_color = Color.Empty;
            Color databar_border_color = Color.Empty;

            for (int j = 0; j < databars[i].ChildNodes.Count; j++)
                if (databars[i].ChildNodes[j].LocalName == "cfvo" && databars[i].ChildNodes[j].Attributes["type"] != null)
                {
                    if (string.IsNullOrEmpty(left_type))
                        left_type = databars[i].ChildNodes[j].Attributes["type"].Value;
                    else if (string.IsNullOrEmpty(right_type))
                        right_type = databars[i].ChildNodes[j].Attributes["type"].Value;

                    if (databars[i].ChildNodes[j].Attributes["val"] != null)
                        if (string.IsNullOrEmpty(left_val))
                            left_val = databars[i].ChildNodes[j].Attributes["val"].Value;
                        else if (string.IsNullOrEmpty(right_val))
                            right_val = databars[i].ChildNodes[j].Attributes["val"].Value;
                }
                else if (databars[i].ChildNodes[j].LocalName == "color")
                {
                    color = databars[i].ChildNodes[j].Attributes["rgb"].Value;
                    int argb = Int32.Parse(color, System.Globalization.NumberStyles.HexNumber);
                    databar_fill_color = Color.FromArgb(argb);

                    databar_border_color = Color.FromArgb(255,
                        databar_fill_color.R - 50 < 0 ? databar_fill_color.R + 50 : databar_fill_color.R - 50,
                        databar_fill_color.G - 50 < 0 ? databar_fill_color.R + 50 : databar_fill_color.G - 50,
                        databar_fill_color.B - 50 < 0 ? databar_fill_color.R + 50 : databar_fill_color.B - 50);
                }

            string temp_conditional_formatting_template = @"<x14:conditionalFormatting xmlns:xm=""http://schemas.microsoft.com/office/excel/2006/main"">
        <x14:cfRule type=""dataBar"" id=""{" + temp_databar_id + @"}"">
            <x14:dataBar minLength=""" + (string.IsNullOrEmpty(left_val) ? "0" : left_val) + "\" maxLength=\"" + (string.IsNullOrEmpty(right_val) ? "100" : right_val) + "\" gradient=\"0\" " + (databar_border_color.IsEmpty ? string.Empty : "border = \"1\"") + ">";

            temp_conditional_formatting_template += Environment.NewLine + "<x14:cfvo type=\"" + (left_type.ToLower() == "min" ? "autoMin" : left_type) + "\" />";
            temp_conditional_formatting_template += Environment.NewLine + "<x14:cfvo type=\"" + (right_type.ToLower() == "max" ? "autoMax" : right_type) + "\" />";

            if (!databar_border_color.IsEmpty)
                temp_conditional_formatting_template += Environment.NewLine + "<x14:borderColor rgb=\"" + BitConverter.ToString(new byte[] { databar_border_color.A, databar_border_color.R, databar_border_color.G, databar_border_color.B }).Replace("-", "") + "\" />";

            temp_conditional_formatting_template += Environment.NewLine + @"</x14:dataBar>
        </x14:cfRule>
        <xm:sqref>" + temp_sqref + @"</xm:sqref>
    </x14:conditionalFormatting>";

            conditional_formattings_str += temp_conditional_formatting_template;
        }

        databars[0].ParentNode.ParentNode.ParentNode.InnerXml += @"<extLst>
<ext uri=""{78C0D931-6437-407d-A8EE-F0AAD7539E65}"" xmlns:x14=""http://schemas.microsoft.com/office/spreadsheetml/2009/9/main"">
<x14:conditionalFormattings>" + conditional_formattings_str + @" 
</x14:conditionalFormattings>
</ext>
</extLst>";
    }
}

并且这确实使数据栏成为可靠的填充,问题是其他任何条件格式(例如,Greaterthan都为true时会丢失其样式)。>>

例如,我添加数据栏和大于123(绿色)的条件格式。Excel仍会看到标准格式规则大于123,但是样式为true时未设置样式(未设置绿色)。同时正确显示数据栏。

我不知道在哪里看……有人帮忙!

EPPlus不支持extLst,而使用固态填充使数据栏条件格式化是必需的。它们本身是渐变的,没有修改。我对此进行了编码,以修改工作表'...

这就是黑客的问题-它们是如此脆弱! :)
