asp.net 下载文件如何使文件下载到指定的文件夹中

Answer 1

用SaveFileDialog对象。

private void SaveButton_Click(object sender, EventArgs e) { 

SaveFileDialog saveFileDialog1 = new SaveFileDialog(); saveFileDialog1.InitialDirectory = @"C:\"; saveFileDialog1.Title = "Save text Files"; 

saveFileDialog1.CheckFileExists = true; 

saveFileDialog1.CheckPathExists = true; 

saveFileDialog1.DefaultExt = "txt";

 saveFileDialog1.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";

 saveFileDialog1.FilterIndex = 2; saveFileDialog1.RestoreDirectory = true;

 if (saveFileDialog1.ShowDialog() == DialogResult.OK) 

{ textBox1.Text = saveFileDialog1.FileName; } 

}
