如何从.NET DataGridView控件的单元格值写入文本文件？ [英] How to write a text file from a .NET DataGridView control cell values?

问题描述

下面的代码应该循环遍历 DataGridView 中的所有行，并将所有单元格值写入文本文件中。

但是，它会输出所有的行，但只输出每个行的第一个单元格，而不是其他三个单元格。

I have the following code that should loop through all the rows in my DataGridView, and write all their cell values to a text file.
However, it outputs all the rows, but only the first cell of each one, and not the other three cells.

string file_name = "C:\\test1.txt";

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

int count = dgv.Rows.Count;

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

objWriter.Close();

推荐答案

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

        }
        // record seperator could be written here.
    }

虽然使用foreach循环会更干净。

Although, it would be cleaner if you used a foreach loop.
