DataGrid列表信息保存为EXCEL到指定的路径

许多WPF或者Winform程序在保存数据时，会以EXCEL或者文本的形式展现可视化界面的数据，本文就简单介绍下将DataGrid列表信息保存为EXCEL到指定的路径下，例子很简单，用的着的直接用吧。

没有太多的理论性东东，下面直接为大家展现实例。

1.先添加一个按钮用于选择保存路径

 1    private void button3_Click(object sender, EventArgs e)
 2         {
 3             string saveFileName = "";
 4             SaveFileDialog saveDialog = new SaveFileDialog();
 5             saveDialog.DefaultExt = "xls";
 6             saveDialog.Filter = "Excel文件|*.xls";
 7             saveDialog.FileName = "领用历史记录";
 8             saveDialog.ShowDialog();
 9             saveFileName = saveDialog.FileName;
10             ExportExcels(saveFileName, dataGridView1);
11         }

2.下面时将Datagridview显示的数据转化为EXCEL并保存到路径

 1     private void ExportExcels(string fileName, DataGridView myDGV)
 2         {
 3            
 4             if (fileName.IndexOf(":") < 0) return; //被点了取消
 5             Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
 6             if (xlApp == null)
 7             {
 8                 MessageBox.Show("无法创建Excel对象，可能您未安装Excel");
 9                 return;
10             }
11             Microsoft.Office.Interop.Excel.Workbooks workbooks = xlApp.Workbooks;
12             Microsoft.Office.Interop.Excel.Workbook workbook = workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet);
13             Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];//取得sheet1
14             //写入标题
15             for (int i = 0; i < myDGV.ColumnCount; i++)
16             {
17                 worksheet.Cells[1, i + 1] = myDGV.Columns[i].HeaderText;
18             }
19             //写入数值
20             for (int r = 0; r < myDGV.Rows.Count; r++)
21             {
22                 for (int i = 0; i < myDGV.ColumnCount; i++)
23                 {
24                     worksheet.Cells[r + 2, i + 1] = myDGV.Rows[r].Cells[i].Value;
25                 }
26                 System.Windows.Forms.Application.DoEvents();
27             }
28             worksheet.Columns.EntireColumn.AutoFit();//列宽自适应
29             if (fileName != "")
30             {
31                 try
32                 {
33                     workbook.Saved = true;
34                     workbook.SaveAs(fileName);
35                 }
36                 catch (Exception ex)          
37                 {
38                     MessageBox.Show("导出文件时出错,文件可能正被打开！\n" + ex.Message);
39                 }
40            }
41             xlApp.Quit();
42             workbook.Close();
43             GC.Collect();//强行销毁
44             MessageBox.Show("文件： " + fileName + ".xls 保存成功", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
45 
46         }
