我正在检查我的 FTP 服务器上是否存在目录:
public bool DirectoryExists(string directory)
{
bool directoryExists;
var request = (FtpWebRequest)WebRequest.Create(directory);
request.Method = WebRequestMethods.Ftp.ListDirectory;
request.Credentials = new NetworkCredential("user", "pass");
try
{
using (request.GetResponse())
{
directoryExists = true;
}
}
catch (WebException)
{
directoryExists = false;
}
return directoryExists;
}
在这种情况下:
directory = @"ftp://ftp.example.com/Rubicon";
在我的服务器上,我有一个名为Rubicon1
. 这导致我的支票退回true
。除非它与目录名称完全匹配,否则如何确保它失败?
