Question

I am importing a source file and processing it and then after that I have to save it in a new location. I have created the syntax for importing file, tell me the syntax to save it to a new location. One is when I am calling the constructor to give the path of import file, then I can also give the path for the output location. But don't know how to implement it. Please tell.

Answer 1

You can use a SaveFileDialog pretty much like this:

using ( var dlg = new SaveFileDialog() )
{
    if ( dlg.ShowDialog() == DialogResult.OK )
    {
        //SAVE THE OUTPUT
        //DEPENDING ON THE FORMAT, YOU MAY WANT TO USE
        //File.WriteAllBytes(dlg.FileName, yourBytes);
        //File.WriteAllText(dlg.FileName, yourText);
        //File.WriteAllLines(dlg.FileName, yourStringArr);
        //OR ANY OTHER CODE YOU WANT TO USE TO PERSIST YOUR DATA
    }
        //else the user clicked Cancel
}

Also, you can set a default extension, a default path and more. Look up SaveFileDialog's information on MSDN

导入文件时，可以使用StreamWriter基类将其写入最终用户在文本框或文件上传框中指定的文件。
