C#在桌面上保存txt文件

如何保存我在桌面上创建的txt文件?

这是代码:

void CreaTxtBtnClick(object sender,EventArgs e){ string filePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop); filePath = filePath + @”\Error Log\”; TextWriter sw = new StreamWriter(@”Gara.txt”); int rowcount = dataGridView1.Rows.Count; for(int i = 0; i < rowcount – 1; i++){ sw.WriteLine( dataGridView1.Rows[i].Cells[0].Value.ToString() + ‘\t’ + dataGridView1.Rows[i].Cells[1].Value.ToString() + ‘\t’ + dataGridView1.Rows[i].Cells[2].Value.ToString() + ‘\t’ + dataGridView1.Rows[i].Cells[3].Value.ToString() + ‘\t’ + dataGridView1.Rows[i].Cells[4].Value.ToString() + ‘\t’ + dataGridView1.Rows[i].Cells[5].Value.ToString() + ‘\t’ + dataGridView1.Rows[i].Cells[6].Value.ToString() + ‘\t’ + dataGridView1.Rows[i].Cells[7].Value.ToString() + ‘\t’ ); } sw.Close(); Message@R_946_2419@.Show(“File txt creato correttamente”);}

我按照这些指示思考

Environment.GetFolderPath(Environment.SpecialFolder.Desktop);filePath = filePath + @”\Error Log\”;TextWriter sw = new StreamWriter(@”Gara.txt”);

我可以将文件保存在桌面上,但是在错误的路径中正确创建了txt.
我该如何解决?

解决方法 您已构建了filePath,但尚未在TextWriter中使用它.相反,您只需要写入Gara.txt文件,该文件默认位于应用程序启动的文件夹中.

将您的代码更改为:

filePath = filePath +@”\Error Log\Gara.txt”; TextWriter sw= new StreamWriter(filePath);
