Question

我创建了一个具有自定义集合属性（Tabs）的自定义Web部件。当您在编辑模式下编辑和保存自定义属性时（通过浏览器），Web部件可以正常工作。我想使用Web服务更新我的自定义Web部件，因此我导出了Web部件并获取了xml内容并按原样传递（因此我可以轻松地测试它），但是发生了错误

The file you imported is not valid. 
Verify that the file is a Web Part description file (*.webpart or *.dwp) and that it contains well-formed XML.

我已经使用在线xml验证器验证了xml并删除了此语句

<?xml version="1.0" encoding="utf-16"?>

因为这是根据XML验证器导致不良的formex XML的那个，但仍然没有运气，发生了同样的错误。

任何想法？我无法弄清楚Tabs属性上的XML有什么问题。

代码：

    string webPartXml = string.Empty;
    string pageUrl = currenturl;

        Guid storageKey = new Guid(webpartid);

        using (StreamReader sr = new StreamReader(@"C:\tab.txt"))
        {            
            webPartXml = sr.ReadToEnd();                
        }
        webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">");

        try
        {
            svc.SaveWebPart2(pageUrl, storageKey, webPartXml, WebpartpagesSvc.Storage.Shared, false);
        }catch(Exception err)
        {
            throw;
        }

我认为这是当你尝试将xml恢复到破坏它的原始版本时。你真的需要这行代码吗？

webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">");

如果将其删除会怎样？如果它不起作用，我建议将值包装在CDATA标签中以便转义xml：

string startTabProperty = @"<property name=""Tabs"" type=""Test.Tabs, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c9e6068352095bx6"">";
string endTabProperty = "></property>"; //Note the >< in order to identify correct place
webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">"); 
webPartXml = webPartXml.Replace(startTabProperty, startTabProperty + "<![CDATA[");
webPartXml = webPartXml.Replace(endTabProperty , ">" + "]]>" + "</property>");

祝你好运！
