Question

我编写了以下代码，但它不起作用（它在我的CSV文件中保存了愚蠢的东西）。有什么不对？我的DataGridView中有两列。

var strValue = new StringBuilder();

foreach(DataGridViewRow row in dataGridView1.Rows)
{
    strValue.AppendLine(row.Cells[0] + "," + row.Cells[1]);
}

string strFile = Properties.Settings.Default.AutoCompleteFile; //File Path

if (!string.IsNullOrEmpty(strValue.ToString()))
{
    File.WriteAllText(strFile, strValue.ToString(), Encoding.UTF8);
}

这是我在保存文件中得到的结果：

当你这样称呼时：

strValue.AppendLine(row.Cells[0] + "," + row.Cells[1]);

.Net正在每个单元格上执行“ToString”，而不是它们的值。这是row.Cells[x]：http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.aspx

的类型

使用Value属性可能会解决您的问题：

strValue.AppendLine(row.Cells[0].Value + "," + row.Cells[1].Value);

将DataGridView导出为CSV文本文件
