如何在文本文件中写入datagrindview中的内容

问题描述

我想知道如何在文本修复程序中写入在datagrindview中写入的数据.

这是我用来在datagrindview中编写的代码:

I would like to know how I can write in a text fixer the data that is written in my datagrindview.

This is the code I use to write in my datagrindview:

string connString = @"Data source = teste1234 ; Database=1234 ; User Id=test ; Password=test123";

            using (SqlConnection sqlConn = new SqlConnection(connString))
            {
                string sqlQuery = @"SELECT * from Zone";
                SqlCommand cmd = new SqlCommand(sqlQuery, sqlConn);
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                DataTable table = new DataTable();
                da.Fill(table);
                dataGridView1.DataSource = new BindingSource(table, null);
            }

我尝试过的事情:

我尝试过了，但是没有用.

What I have tried:

I tryed this but it dont work.

public void WriteToTextFile (DataGridView dgv)
        {
            string file_name = "D:\\test1.txt";

        System.IO.StreamWriter objWriter;

        objWriter = new System.IO.StreamWriter(file_name);

        int count = dgv.Rows.Count;
        for (int row = 0; row < count-1; row++)
        {
            int colCount = dgv.Rows[row].Cells.Count; 

            for ( int col = 0; col < colCount-1; col++)  
            {
                objWriter.WriteLine(dgv.Rows[row].Cells[col].Value.ToString());
            }

        }
        objWriter.Close();
        }
