将datagridveiw值保存为csv文件或excel文件格式 [英] save datagridveiw values in csv file or excel file format

问题描述

开发人员，

我是沙尔玛·沙尔
我正在使用数据集将csv文件加载到datagridview中，并对它们执行一些操作.毕竟，我想将datagridview保存为csv文件格式，如果用户想要使用excel格式.

我打开了一个对话框，以csv文件或excel文件格式保存数据.
问题是我没有代码将datagridview保存为csv文件或excel文件格式.

如果用户要在任何位置保存具有相同文件名或其他名称的数据，我还希望以前的csv文件名自动显示在保存"对话框中.

请立即提供解决方案

Hi developers,

if (!string.IsNullOrEmpty(dataGridView1[j, i].Value.ToString()))

if (j > 0)
strValue = strValue + "," + dataGridView1[j, i].Value.ToString();
