Do you know how to correct my C# .Net code to make a Sybase ODBC connection from a windows form?

I am developing a C# .Net Windows application using Visual Studio 2005.
I need to call Sybase Stored Procedures from the application.
I use a Sybase ODBC connection as follows:

User Data Sources
------------------------
Name  NYP              Driver   DataDirect 4.0 Sybase WIre Protocol

I have created the following code so far:

private void stored_procedure1()
        {
            OdbcConnection _cn = new OdbcConnection("Data Source=NYP;Database=ap;User ID=PW;Password=XX;");                                
            _cn.Open();
            System.Data.SqlClient.SqlCommand comm2 = _cn.CreateCommand();
            comm.CommandType = System.Data.CommandType.StoredProcedure;
            comm.CommandText = string.Format("sp3D_GetListOfDocuments");
            System.Data.DataSet dataSet = new System.Data.DataSet();
            System.Data.SqlClient.SqlDataAdapter sqlDataAdapter = new System.Data.SqlClient.SqlDataAdapter(comm2);
            sqlDataAdapter.Fill(dataSet);
--------------------------------------------------
I get the following error:

Error:
Cannot implicitly convert type 'System.Data.Odbc.OdbcCommand' to 'System.Data.SqlClient.SqlCommand'      

The error is on the following line:
 System.Data.SqlClient.SqlCommand comm2 = _cn.CreateCommand();

Do you know how I can fix this error and do you see any other problems with this code ?
