C# 以编程方式创建ftp站点

C# 以编程方式创建ftp站点,c#,ftp,C#,Ftp,我已经写了代码,以创建新的网站在ftp。但这给了com一个例外。随附代码以供参考 例外情况详情如下: System.Runtime.InteropServices.COMException was unhandled Message="Filename: \r\nError: Unrecognized element 'ftpServer'\r\n\r\n" Source="" ErrorCode=-2147023483 StackTrace: at Microso

您可以从异常中判断错误是什么。查看异常堆栈跟踪中的第一行:

System.Runtime.InteropServices.COMException 未处理消息=“文件名: \r\n错误:无法识别的元素 “ftpServer”\r\n\r\n“Source=” 错误代码=-2147023483

首先,我们看到“unrecognedelement'ftpserver'”——这应该告诉我们在查看代码时发生了什么。但除此之外,我们还收到一个错误代码,告诉我们抛出COMException的确切原因。如果我们将错误代码解码为无符号整数(十六进制),我们得到:

这对应于以下错误代码:

  • 8:失败
  • 7:Win32
  • 585:(1413十进制):无效索引(错误\u无效\u索引)
有关错误代码的详细信息,请参阅和

因此,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'”。查看您的代码,您可以通过告诉sitesCollection添加一个名为“site”的新元素来创建一个新的ConfigurationElement siteElement:

然后为站点创建名称,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,您随后尝试使用名称“ftpServer”获取站点的子元素:

但是,刚刚创建的ConfigurationElement siteElement没有名为ftpServer的子级!所以我们得到一个无效的索引并抛出一个异常。您的意思是在这行代码中创建一个子元素吗


另一方面,我认为这是一个COMException,因为.NET接口与底层IIS7 COM对象的互操作。不是Microsoft.Web命名空间的专家(根本不是),这只是猜测。
