LINQ to SQL how to write a method that checks if a row exists when we have multiple tables

I am trying to write a method in C # that can take as parameter tabletype, column and column value and check if it got a row with a value with a value

the method looks like this:

public object GetRecordFromDatabase(Type tabletype, string columnname, string columnvalue)

      

        
        
        
      

    

I am using LINQ to SQL and need it in a generic way, so I don't have to write every table I get into the DB.

I've been doing this so far for every table, but over 70 of them get cumbersome and boring.

Is there a way to generate the following code dynamically and change the copied table names with values ​​from the parameter list? In this example, I have a table in the DB called tbl_nation which DataContext pluralizes to tbl_nations and I check the column for the value

if (DB.tbl_nations.Count (c => c.code.Equals (columnvalue)) == 1)
            {
                return DB.tbl_nations.Single (c => c.code.Equals (columnvalue));
            }
