我正在尝试使用Microsoft diff和patch gui工具。执行语句 dv.load 时，我收到错误：缺少选项属性
XmlDiffPatch.View 中发生了类型为"System.Exception"的未处理异常.dll
其他信息：差异图中缺少"选项"属性。

尝试将选项传递给XmlDiff构造函数：
XmlDiff xmldiff = new XmlDiff(XmlDiffOptions.IgnoreChildOrder |
XmlDiffOptions.IgnoreNamespaces |
XmlDiffOptions.IgnorePrefixes);
因此，请像这样重新排列您的代码：
XmlDiffOptions diffOptions = new XmlDiffOptions();
diffOptions = XmlDiffOptions.None;
//Read the options settings and OR the XmlDiffOptions enumeration.
diffOptions = diffOptions | XmlDiffOptions.IgnorePI;
diffOptions = diffOptions | XmlDiffOptions.IgnoreChildOrder;
diffOptions = diffOptions | XmlDiffOptions.IgnoreComments;
diffOptions = diffOptions | XmlDiffOptions.IgnoreDtd;
diffOptions = diffOptions | XmlDiffOptions.IgnoreNamespaces;
diffOptions = diffOptions | XmlDiffOptions.IgnorePrefixes;
diffOptions = diffOptions | XmlDiffOptions.IgnoreWhitespace;
diffOptions = diffOptions | XmlDiffOptions.IgnoreXmlDecl;
diff.Algorithm = XmlDiffAlgorithm.Auto;
XmlDiff diff = new XmlDiff(diffOptions);
