用户上传的文件不符合样版文件。列名不一致。需要想出一个方法，去判断Excel的表头字段。下面方法是检查出Excel结构，需要使用GetOleDbSchemaTable方法进行处理。

 //oleDBconnection http://www.cnblogs.com/insus/articles/2008946.html
        string ec = objKQ.GetExcelConnectionString("~/Temp/49be9717-ed46-4f1e-8302-4d23efe4db93.xlsx");
       
        OleDbConnection oc = new OleDbConnection(ec);
        oc.Open();
        String[] restrections = { null, null, "Sheet1$", null };
        DataTable oDt = oc.GetOleDbSchemaTable(OleDbSchemaGuid.Columns,restrections);
        oc.Close();

结果：

到此为止，只是找到Excel文件的Schema，接下来是需要处理得到的结果是否是您要求的字段了。

 String[] excelColumn = new String[oDt.Rows.Count];
        int i = 0;

        foreach (DataRow row in dt.Rows)
        {
            excelColumn[i] = row["COLUMN_NAME"].ToString();
            i++;
        }

        for (int j = 0; j < excelColumn.Length; j++)
        {
            //这里比自己的字段。
        }
