如何从.NET DataGridView控件的单元格值写入文本文件？

Question

我有以下代码应循环遍历我的DataGridView中的所有行，并将其所有单元格值写入文本文件。
但是，它输出所有行，但只输出每个行的第一个单元格，而不是其他三个单元格。

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(); 

Answer 1

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. 
    } 

尽管如此，如果你使用了foreach循环这将是清洁的。

Answer 2

TextWriter sw = new StreamWriter(@"D:\\file11.txt"); 

     int rowcount = dataGridViewX1.Rows.Count; 
     for (int i = 0; i < rowcount - 1; i++) 
     { 

      sw.WriteLine(dataGridViewX1.Rows[i].Cells[0].Value.ToString()); 
     } 
     sw.Close(); 


     MessageBox.Show("Text file was created.");
