Question

我有list

   public List<string> strImportRequiredFields = new List<string> { "ENTRY/CMD #", "PART #", "REFERENCE 1", "REFERENCE 2", "REFERENCE 3", "DUTY PER" };

现在这是我的代码

  string strFilter = string.Join(" = ' ' OR ", new UploadFields().strImportRequiredFields.Select(x => "[" + x.ToString() + "]").ToArray());
  strFilter += " = ' '";

没有过滤器正在运行并提供所有行

过滤值

“[ENTRY / CMD＃] =''或[PART＃] =''或[参考1] =''或 [参考2] =''或[参考3] =''或[DUTY PER] =''“

 string xlConn = "";
 string strPath = System.Configuration.ConfigurationManager.AppSettings["UploadPath"];
 xlConn = new UploadFields().returnConnectionForCSV(strPath);
 OleDbConnection oledb_conn = null;
 oledb_conn = new OleDbConnection(xlConn);
 OleDbDataAdapter oledb_ad = new OleDbDataAdapter("SELECT * FROM [" + Path.GetFileName(filename) + "]" + " Where " + strFilter , oledb_conn);
 DataTable dtImport = new DataTable();
 oledb_ad.Fill(dtImport);

抛出错误

标准表达式中的数据类型不匹配。

相同的代码适用于Xlsx

任何建议

标准不匹配通常意味着您尝试放入数据库或查询的数据无法被接受，因为数据库需要不同类型的数据。在您的情况下，您的查询需要匹配每个字段类型
