Method to check if Value exists in a Column of a Table, where all three (TableName,ColumnName and ColumnValue) are parameters

When working with LINQ to SQL you might get stuck with a problem when required to check if Value exists in a Column of a Table, where all three (TableName,ColumnName and ColumnValue) are parameters. If that Table is mapped/dropped in the .dbml file then with the help of this method would actually get the solution.

The code does the following:
----------------------------------------------------------------------------------
Instantiated an object of DataContext by passing the ConnectionString.
Checked if the Table exists, within all the Tables of the DataContext.
If its found, then checked if Column exists within the Columns of the Table.
If its found, then called a Generic Method of the Type Table and checked if the Value exists in that Column of that Table.

Solve:
