c#中的MMC开发

本文关键字：开发 MMC 中的 | 更新日期: 2023-09-27 18:07:48

你好，我正在用c#开发MMC snap，

在这个我想读取XML文件，所以在哪里放我的XML文件。

代码没有给出任何构建错误，但当我在MMC中添加snapin时，它给出了错误该怎么做。

[SnapInSettings("{2078B103-76FF-46E1-95BB-8B2CE3A72E60}", 
     DisplayName = "Configuration", 
     Description = "abc Pvt Ltd.")
    ]
    public class Mymmc : SnapIn
    {
        XDocument xDoc;
        public Sararmmc()
        {
            ScopeNode childscopenode;
            xDoc = XDocument.Load("MMCSnapinXML.xml");
            IEnumerable<XElement> xelements = xDoc.Root.Descendants();
            this.RootNode = new ScopeNode();
            this.RootNode.DisplayName = xDoc.Root.Attribute("name").Value;
            foreach (XElement elm in xelements)
            {
                childscopenode = new ScopeNode();
                childscopenode.DisplayName = elm.Attribute("name").Value;
                this.RootNode.Children.Add(childscopenode);
            }
        }
    }

我正在得到异常已被调用的目标抛出。

c#中的MMC开发

在构造函数中可能抛出许多异常(堆栈跟踪表明这是错误的来源)。可能是在XDocument上抛出了格式错误的XML异常。加载，如果您正在访问的任何命名节点/属性不存在，也可能是空引用异常。它可能是一个未找到的文件异常，或者甚至是一个安全异常——它甚至可能是一些更模糊的东西，比如MMC要求你的程序集签名。在不知道你遇到了什么类型的异常的情况下，任何人都很难帮助你!

正如我在评论中所说，当您在运行时收到无法轻易解释的错误时，在应用程序中进行详细的日志记录就变得非常有价值了!NLog和log4net是。net应用程序中最流行的两个日志框架
