Question

In My Code i am passing string result value to my stored procedure

try
{
using (SqlStoredProcedure sspObj = new SqlStoredProcedure("dbo.usp_CloseEvent", Connection, CommandType.StoredProcedure))
{
sspObj.AddParameterWithValue("@Close", SqlDbType.VarChar, 0, ParameterDirection.Input, result);
sspObj.ExecuteNonQuery();
sspObj.Dispose();
}
}
catch (Exception xObj)
{
Console.WriteLine("Error >> " + xObj.Message);
}

Default SqlDbType.VarChar Size is 1 to 8000 characters. My Question is What if my string variable result has size more than 8000 characters

And what is solution for this ?

My Stored Procedure Look like this

ALTER PROCEDURE [dbo].[usp_CloseEvent]
    @Close      VarChar(Max)
AS

SqlStoredProcedure.cs

virtual public SqlParameter AddParameterWithValue(string parameterName,
            SqlDbType dbType,
            int size,
            ParameterDirection direction,
            object value) {

            SqlParameter p = this.AddParameter(parameterName, dbType, size, direction);

            if (value == null) {
                value = DBNull.Value;
            }

            p.Value = value;

            return p;
        }

Database is SQL SERVER 2008

For a VARCHAR(MAX), you need to pass -1 as the size when adding a parameter.
