Finally, the problem of getting output parameters using sqldatareader is solved! The root cause is that you do not have a deep understanding of the sqldatareader data reader! Let's take a look at my example: Create procedure h_transfer ( @ Returnvalue varchar (10) Output ) As Declare @ isanswer char (2) Select @ isanswer = isanswer from question If (isanswer = 1) Begin Set @ returnvalu = 'handled' End Else (isanswer = 0) Begin Set @ retur

In general, we use ADO. NET to query the database and return the generic set; and use SqlDataReader to read data and store the data to the object row by row.
