I have this stored procedure

CREATE PROCEDURE [dbo].InsertUserTables
@UserName varchar(100),
@View varchar(30)
AS


INSERT INTO [dbo].[UserTables] (
[UserName],
[View]
)
VALUES (
@UserName,
@View
)
GO



and the C# code to insert a row

Code:
    System.Data.SqlClient.SqlParameter [] arParams2 = new      System.Data.SqlClient.SqlParameter[2];

    arParams[0] = new System.Data.SqlClient.SqlParameter("@UserName", System.Data.SqlDbType.NVarChar, 100);

    arParams[0].Value = "awni";
    arParams[0].Direction = System.Data.ParameterDirection.Input;

      arParams[1] = new System.Data.SqlClient.SqlParameter("@View", System.Data.SqlDbType.NVarChar, 30);

      arParams[1].Value = "Cars";
      arParams[1].Direction = System.Data.ParameterDirection.Input;

      Insert("InsertUserTables", arParams);


..........


public void Insert(string szSPName, SqlParameter [] arParms)
{		


// SqlConnection that will be used to execute the sql commands
SqlConnection connection = null;
connection = GetConnection(CGlobals.szConnectionString);


SqlCommand sqlCmd = new SqlCommand(szSPName, connection); 
sqlCmd.CommandType = CommandType.StoredProcedure; 

//sqlCmd.Connection.Open(); 

foreach (SqlParameter p in arParms)
{

if( p != null )
{
// Check for derived output value with no value assigned
if ( ( p.Direction == ParameterDirection.InputOutput || 
p.Direction == ParameterDirection.Input ) && 
(p.Value == null))
{

p.Value = DBNull.Value;
}
sqlCmd.Parameters.Add(p);
}
}


sqlCmd.ExecuteNonQuery(); 

connection.Close();
}


I've omitted the try/catch blocks here, but in the my code, I use them and
I get "Object must implement IConvertible" exception, what can I do? What
object is it talking about? 

thanks
