C#/.NET-文件夹&文件重命名(非复制copy+删除delete)

用法如下

                //文件夹重命名
                Computer myComputer = new Computer();
                myComputer.FileSystem.RenameFile(fullFilePath, newFileName);
                myComputer.FileSystem.RenameDirectory(fullDirPath, newName);        

解释一下用法，

fullFilePath 是文件的完整路径，

fullDirPath 是文件夹的完整路径；

newFileName 和 newName 是要改的名字，不需要加路径。

看一下文档，如下：

RenameFile：

    /// <summary>Renames a file.</summary>
    /// <param name="file">File to be renamed.</param>
    /// <param name="newName">New name of file.</param>
    /// <exception cref="T:System.ArgumentException">
    /// <paramref name="newName" /> contains path information or ends with a backslash (\).</exception>
    /// <exception cref="T:System.ArgumentNullException">
    ///         <paramref name="file" /> is <see langword="Nothing" />.
    /// -or-
    /// <paramref name="newName" /> is <see langword="Nothing" /> or an empty string.</exception>
    /// <exception cref="T:System.IO.FileNotFoundException">The file does not exist.</exception>
    /// <exception cref="T:System.IO.IOException">There is an existing file or directory with the name specified in <paramref name="newName" />.</exception>
    /// <exception cref="T:System.IO.PathTooLongException">The path exceeds the system-defined maximum length.</exception>
    /// <exception cref="T:System.NotSupportedException">A file or directory name in the path contains a colon (:) or is in an invalid format.</exception>
    /// <exception cref="T:System.Security.SecurityException">The user lacks necessary permissions to view the path.</exception>
    /// <exception cref="T:System.UnauthorizedAccessException">The user does not have required permission.</exception>
    public void RenameFile(string file, string newName)
    {
      Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(file, newName);
    }

RenameDirectory：

    /// <summary>Renames a directory.</summary>
    /// <param name="directory">Path and name of directory to be renamed.</param>
    /// <param name="newName">New name for directory.</param>
    /// <exception cref="T:System.ArgumentException">
    /// <paramref name="newName" /> contains path information.</exception>
    /// <exception cref="T:System.ArgumentNullException">
    ///         <paramref name="directory" /> is <see langword="Nothing" />.
    /// -or-
    /// <paramref name="newName" /> is <see langword="Nothing" /> or an empty string.</exception>
    /// <exception cref="T:System.IO.DirectoryNotFoundException">The directory does not exist.</exception>
    /// <exception cref="T:System.IO.IOException">There is an existing file or directory with the name specified in <paramref name="newName" />.</exception>
    /// <exception cref="T:System.IO.PathTooLongException">The path exceeds the system-defined maximum length.</exception>
    /// <exception cref="T:System.NotSupportedException">A file or directory name in the path contains a colon (:) or is in an invalid format.</exception>
    /// <exception cref="T:System.Security.SecurityException">The user lacks necessary permissions to view the path.</exception>
    /// <exception cref="T:System.UnauthorizedAccessException">The user does not have required permission.</exception>
    public void RenameDirectory(string directory, string newName)
    {
      Microsoft.VisualBasic.FileIO.FileSystem.RenameDirectory(directory, newName);
    }

使用时，需要添加引用

using Microsoft.VisualBasic.Devices;

以及下图的，Microsoft.VisualBasic也是必不可少的。
