我已经编写了代码来在ftp中创建新站点。但它给予了例外。附上代码以供参考。

答案 0 :(得分:5)
您可以从异常中判断出错误是什么。查看异常堆栈跟踪中的第一行:
System.Runtime.InteropServices.COMException 未处理的消息=“文件名: \ r \ n错误:无法识别的元素 'ftpServer'\ r \ n \ r \ n“来源=”“ 错误码= -2147023483
首先,我们看到“无法识别的元素'ftpserver'” - 这应该告诉我们很多关于我们查看代码时发生的事情。但除此之外,我们还提供了一个错误代码,告诉我们为什么抛出COMException。如果我们将错误代码解码为unsigned int(hex),我们得到:
0x80070585
这对应于错误代码:
有关错误代码的详细信息,请参阅HRESULT和Win32 error codes。
所以,我们抛出了一个COMException,因为我们使用了无效的索引。我们在异常消息中得到一个“无法识别的元素'ftpServer'”。查看代码,通过告诉sitesCollection添加名为“site”的新元素来创建新的ConfigurationElement siteElement:
Microsoft.Web.Administration.Configuration config = serverManager.GetApplicationHostConfiguration();
ConfigurationSection sitesSection = config.GetSection("system.applicationHost/sites");
ConfigurationElementCollection sitesCollection = sitesSection.GetCollection();
ConfigurationElement siteElement = sitesCollection.CreateElement("site");
然后,您可以为站点创建名称,并在站点的绑定集合中创建绑定:
siteElement["name"] = @"eMentorftp";
ConfigurationElementCollection bindingsCollection = siteElement.GetCollection("bindings");
ConfigurationElement bindingElement = bindingsCollection.CreateElement("binding");
bindingElement["protocol"] = @"ftp";
bindingElement["bindingInformation"] = @"*:21:";
bindingsCollection.Add(bindingElement);
不幸的是,您尝试使用名称“ftpServer”获取网站的子元素:
ConfigurationElement ftpServerElement = siteElement.GetChildElement("ftpServer");
但是,刚刚制作的ConfigurationElement siteElement没有名为ftpServer的子节点!所以我们得到一个无效的索引并抛出异常。你的意思是在这行代码中创建一个子元素吗?
顺便说一句,我认为这是一个COMException,因为.NET接口与底层IIS7 COM对象互操作。不是Microsoft.Web命名空间的专家(根本就是),这只是猜测。
