当我运行并选择文件并上传时，错误显示如下



外部表格不是预期的格式。



如何解决此错误外部表格不符合预期格式。



我的尝试：



我的代码如下

when i run and select the file and upload, then error shows as follows

External table is not in the expected format.

how to solve this error "External table is not in the expected format".

What I have tried:

My code as follows

private void ExcelConn(string FilePath)
        {
            constr = string.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=YES;""", FilePath);
            Econ = new OleDbConnection(constr);
       }


 private void connection()
        {
       sqlconn = ConfigurationManager.ConnectionStrings["Constring"].ConnectionString;
            con = new SqlConnection(sqlconn);
        }


 private void InsertExcelRecords(string FilePath)
        {
            ExcelConn(FilePath);
            Query = string.Format("select * FROM [{0}]", "Sheet1
