为你的C# XML工具类添加全局异常处理 让错误处理更集中

public static class XmlHelper
{
    public static event Action<Exception, string> OnError;
<pre class="brush:php;toolbar:false;"><pre class="brush:php;toolbar:false;">private static void HandleException(Exception ex, string operation)
{
    OnError?.Invoke(ex, operation);
}

public static XDocument LoadDocument(string filePath)
{
    try
    {
        return XDocument.Load(filePath);
    }
    catch (FileNotFoundException ex)
    {
        HandleException(ex, $"LoadDocument: 文件未找到 - {filePath}");
        return null;
    }
    catch (XmlException ex)
    {
        HandleException(ex, $"LoadDocument: XML格式错误 - {filePath}");
        return null;
    }
    catch (Exception ex)
    {
        HandleException(ex, $"LoadDocument: 未知错误 - {filePath}");
        return null;
    }
}

// 订阅全局错误
XmlHelper.OnError += (ex, op) =>
{
    MessageBox.Show($"操作失败：{op}\n{ex.Message}");
};
