One of the SqlDbType values. The default is NVarChar.

IDataParameter.DbType

The SqlDbType and DbType are linked. Therefore, setting the DbType changes the SqlDbType to a supporting SqlDbType.

For a list of the supported data types, see the appropriate SqlDbType member. For more information, see DataAdapter Parameters (ADO.NET).

The following example creates a SqlParameter and sets some of its properties.

private static void AddSqlParameter(SqlCommand command, 
    string paramValue)
{
    SqlParameter parameter = new SqlParameter(
        "@Description", SqlDbType.VarChar);
    parameter.Value = paramValue;
    parameter.IsNullable = true;
    command.Parameters.Add(parameter);
}
