Automatically bind column names when calling stored procedures in LINQ

Take the following stored procedure as follows:

Create procedure DBO. sp1
As
Select 'abc'

In C:
VaR o = dB. SP1 ();
Gridview1.datasource = O;
Gridview1.databind ();
No data is obtained.

The reason is that the SELECT statement does not specify a column name, while the LINQ query must contain a column name. However, if you only add a column name to the stored procedure, data still cannot be obtained because in dbdatacontext, the definition of the SP1 function has been bound to the original select function. You must delete the SP1 function and drag it from the database to obtain the data.

From this point of view, it is still a little inconvenient. If the technology can be used in the future, it will be better to automatically update Tables and stored procedures.
