Move a directory in C#
The Directory.Move method moves an existing directory to a new specified directory with full path. The Move method takes two parameters. The Move method deletes the original directory.
The following code snippet moves the source directory to the destination directory.
string sourceDirName = @"C:\Temp";
string destDirName = @"C:\NewTemp";
try
{
Directory.Move(sourceDirName, destDirName);
}
catch (IOException exp)
{
Console.WriteLine(exp.Message);
}
