回答1:

You can look for

SaveFileDialog save = new SaveFileDialog();
save.InitialDirectory = "c:\\MyNewFolder";
save.RestoreDirectory = true;

回答2:

string strPath="c:\MyNewFolder";

if (!Directory.Exists(strPath))

{

    Directory.CreateDirectory(strPath);

}

else

{

//Continue your logic and append your file name

}
