本文实例讲述了C#将Sql数据保存到Excel文件中的方法，非常有实用价值。分享给大家供大家参考借鉴之用。
具体功能代码如下：
public string ExportExcel( DataSet ds,string saveFileName)
{
try
{
if (ds == null)
return "数据库为空";
bool fileSaved = false;
Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
if (xlApp == null)
{
return "无法创建Excel对象，可能您的机子未安装Excel";
}
Microsoft.Office.Interop.Excel.Workbooks workbooks = xlApp.Workbooks;
Microsoft.Office.Interop.Excel.Workbook workbook = workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet);
Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];//取得sheet1
//写入字段
for (int i = 0; i < ds.Tables[0].Columns.Count; i++)
{
worksheet.Cells[1, i + 1] = ds.Tables[0].Columns[i].ColumnName;
}
//写入数值
for (int r = 0; r < ds.Tables[0].Rows.Count; r++)
{
for (int i = 0; i < ds.Tables[0].Columns.Count; i++)
{
worksheet.Cells[r + 2, i + 1] = ds.Tables[0].Rows[r][i];
}
System.Windows.Forms.Application.DoEvents();
}
worksheet.Columns.EntireColumn.AutoFit();//列宽自适应。
if (saveFileName != "")
{
try
{
workbook.Saved = true;
workbook.SaveCopyAs(saveFileName);
fileSaved = true;
}
catch (Exception ex)
{
fileSaved = false;
MessageBox.Show("导出文件时出错,文件可能正被打开！n" + ex.Message);
}
}
else
{
fileSaved = false;
}
xlApp.Quit();
GC.Collect();//强行销毁
if (fileSaved && System.IO.File.Exists(saveFileName)) System.Diagnostics.Process.Start(saveFileName); //打开EXCEL
return "成功保存到Excel";
}
catch (Exception ex)
{
return ex.ToString();
}
}
希望本文所述实例对大家C#程序设计有所帮助。
