C#创建EXCEL表格

首先在。net引用中引用“Microsoft.Office.Interop.Excel”

using MSExcel=Microsoft.Office.Interop.Excel;

 object missing = System.Reflection.Missing.Value;
            MSExcel.Application app = new MSExcel.ApplicationClass();
            app.Application.Workbooks.Add(true);
            MSExcel.Workbook book = (MSExcel.Workbook)app.ActiveWorkbook;
            MSExcel.Worksheet sheet = (MSExcel.Worksheet)book.ActiveSheet;
            sheet.Cells[1, 1] = "源数据站点名称记录";
            sheet.Cells[1, 2] = "匹配总数";
            for (int k = 0; k < 2; k++)
            {
                sheet.Cells[k + 2, 1] = k;
                sheet.Cells[k + 2, 2] = k;
            }
            string n = Server.MapPath("link.xls");
               book.SaveCopyAs(n);
             book.Close(false, missing, missing);
            
             app.Quit();

如果出现：

无法嵌入互操作类型“Microsoft.Office.Interop.Excel.ApplicationClass”。请改用适用的接口

解决办法是将引用的DLL：Microsoft.Office.Interop.Excel;的嵌入互操作类型改为false。
