使用SaveFileDialog将文件保存到c＃中的特定文件夹

Question

我需要使用SaveFileDialog将文件保存到特定文件夹。

例如，保存在“ c：\\ MyNewFolder”中

如果该文件夹存在，则创建并保存；如果该文件夹存在，则仅保存。

        String fileName="";
        String date = DateTime.Now.Day+"-"+DateTime.Now.Month+"-"+DateTime.Now.Year;
        SaveFileDialog saveFileDialog1 = new SaveFileDialog();
        saveFileDialog1.FileName = fileName;
        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {
            using (Stream s = File.Open(saveFileDialog1.FileName,FileMode.CreateNew))

            using (StreamWriter sw = new StreamWriter(s))
            {
                sw.WriteLine(tbName.Text);
                sw.WriteLine(tbSummary.Text);
            }

        }

Answer 1

你可以找

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

Answer 2

string strPath="c:\MyNewFolder";

if (!Directory.Exists(strPath))

{

    Directory.CreateDirectory(strPath);

}

else

{

//Continue your logic and append your file name

}
