给定的ColumnName'ACTUAL DATE'与数据源中的任何列都不匹配

Question

我正在使用sqlBulkCopy将excel文件导入到sql数据库中，但是一旦我开始导入，就会弹出此错误。我正在使用MVC5和EntityFramework6。我已经检查了excel文件和sql表格中的相同列，一切看起来都很好。我已将StgtId设置为我不通过excel表导入的标识字段。我认为，如果我没有记错的话，它将由表格处理。

   public ActionResult Structure(HttpPostedFileBase postedFile)
    {
        string filePath = string.Empty;
        if (postedFile != null)
        {
            string path = Server.MapPath("~/Uploads/");
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }

            filePath = path + Path.GetFileName(postedFile.FileName);
            string extension = Path.GetExtension(postedFile.FileName);
            postedFile.SaveAs(filePath);

            string conString = string.Empty;
            switch (extension)
            {
                case ".xls": //Excel 97-03.
                    conString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString;
                    break;
                case ".xlsx": //Excel 07 and above.
                    conString = ConfigurationManager.ConnectionStrings["Excel07ConString"].ConnectionString;
                    break;
            }

            DataTable dt = new DataTable();
            conString = string.Format(conString, filePath);

            using (OleDbConnection connExcel = new OleDbConnection(conString))
            {
                using (OleDbCommand cmdExcel = new OleDbCommand())
                {
                    using (OleDbDataAdapter odaExcel = new OleDbDataAdapter())
                    {
                        cmdExcel.Connection = connExcel;

                        //Get the name of First Sheet.
                        connExcel.Open();
                        DataTable dtExcelSchema;
                        dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                        string sheetName = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString();
                        connExcel.Close();

                        //Read Data from First Sheet.
                        connExcel.Open();
                        cmdExcel.CommandText = "SELECT * From [" + sheetName + "]";
                        odaExcel.SelectCommand = cmdExcel;
                        odaExcel.Fill(dt);
                        connExcel.Close();
                    }
                }
            }

Answer 1

尝试在名称“ [ACTUAL DATE]”周围添加方括号。

Answer 2

尝试对源列使用序号而不是名称。例如

sqlBulkCopy.ColumnMappings.Add(0, "ActualDate");

受overloads to the SqlBulkCopyColumnMappingCollection.Add() method之一支持。
