Accessing ODBC DSN Data in CLR Procedure using C#/SQL Server

I need to a Select Data from tables accessable via ODBC DSN and bring the result set/DataReader in SQL Server Via CLR Stored Procedure. So I wrote C# Program to create CLR Procdure for that.
As i built and Deploy the Procedure it deployees sucessfully but , in SQL Server Management Studio it gives System.Data.Odbc.OdbcPermission error while Executing procedure.
Code I am using is (is also working in independant C# application) is attahed

The  code Builds and Executes as C# Application but when used in C# Database Project in StoredProcedure Class it builds and deployes but on execution of Stored Procedure from SQL Server Managemen Studio it returns Error

A .NET Framework error occurred during execution of user-defined routine or aggregate "spTestProcsAB":
System.Security.SecurityException: Request for the permission of type 'System.Data.Odbc.OdbcPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
