    Parameters

    command
    The SqlCommand referencing the SQL statement for which the parameter information is to be derived. The derived parameters will be populated into the SqlCommand.Parameters collection of this command.
    Remarks
    DeriveParameters overwrites any existing parameter information for the SqlCommand.

    DeriveParameters requires an extra call to the data server to obtain the information. If the parameter information is known in advance, it is more efficient to populate the parameters collection by setting the information explicitly.

    For more information, see "Using Stored Procedures with a Command" in the Microsoft .NET Framework SDK documentation.
