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();
    MessageBox.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？
