Answer 1

正如其他人提到的那样，您想使用File.Move，但鉴于您的输入，您也想使用Path.Combine并Path.GetFileName 喜欢这样

string str = "C:\\efe.txt";
string dir = "D:\\";
File.Move(str, Path.Combine(dir, Path.GetFileName(str)));

来自 MSDN：如何：复制、删除和移动文件和文件夹（C# 编程指南）：

// Simple synchronous file move operations with no user interface. 
public class SimpleFileMove
{
    static void Main()
    {
        string sourceFile = @"C:\Users\Public\public\test.txt";
        string destinationFile = @"C:\Users\Public\private\test.txt";

        // To move a file or folder to a new location:
        System.IO.File.Move(sourceFile, destinationFile);

        // To move an entire directory. To programmatically modify or combine 
        // path strings, use the System.IO.Path class.
        System.IO.Directory.Move(@"C:\Users\Public\public\test\", @"C:\Users\Public\private");
    }
}

尝试File.Move

using System.IO;
...
string src = "C:\\efe.txt";
string dest = "D:\\efe.txt";
File.Move(src, dest);
