我知道这种查询有很多解决方案,但我无法实现其中任何一种。
我正在将表名传递给我的函数,并希望EF获取传递的相应表值的表结果。
所以这是我在Controller中的函数(JsonResult
): -
public JsonResult FetchTblData()
{
string MyTableName= Request.Form["TblName"].ToString();
using (EBContext db = new EBContext())
{
try
{
var EduTblList = db.(**MyTableName**).ToList(); // want to implement it here.
}
catch (Exception ex)
{
string innerMessage = (ex.InnerException != null) ? ex.InnerException.Message : "";
}
return new JsonResult { Data = EduTblList, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}
}
如果没有太多代码修改和使用EF或LINQ的最简单方法,我怎么能这样做? 请帮助

尝试以下代码:
public JsonResult FetchTblData()
{
string MyTableName= Request.Form["TblName"].ToString();
using (EBContext db = new EBContext())
{
try
{
Type tableType;
switch(MyTableName)
{
case "MyTableName":
tableType= typeof(TableEntityName);
break;
}
var dbquery = context.Set(tableType);
var EduTblList = result.ToList(); // want to implement it here.
}
catch (Exception ex)
{
string innerMessage = (ex.InnerException != null) ? ex.InnerException.Message : "";
}
return new JsonResult { Data = EduTblList, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}
}
