涉及到程序导出Excel报表,所以就花了两个收集了一下资料,这了这个程序,分享给大家.程序说明:
程序读取 gridView 表格中内容,导入到Excel ,自定义 页眉 页脚和添加页码,以及横向打印.列宽根据列的
多少列自适应,表格高度自适应,自动换行等.使用需要添加 引用 Microsoft.Office.Interop.Excel,代码如下 :出处C# 导出 Excel 自定义输出格式
/// <summary>
/// 将GridView内的内容导出到Excel
/// </summary>
/// <param name="xlsName">Excel文件名</param>
/// <param name="gridView">Gridview</param>
public static void ExportToExl(string xlsName, GridView gridView1)

这两天对代码进行的优化,这是优化之后的代码 ,修正一些BUG 和增加导出效率
