Demonstrates

This sample shows how to use the IOrganizationService.ValidateSavedQueryRequest message to validate a FetchXML query, and then use the IOrganizationService.ExecuteByIdSavedQueryRequest message to execute the query.

Example


// Connect to the Organization service. 
// The using statement assures that the service proxy will be properly disposed.
using (_serviceProxy = ServerConnection.GetOrganizationProxy(serverConfig))
{
    // This statement is required to enable early-bound type support.
    _serviceProxy.EnableProxyTypes();

    CreateRequiredRecords();

    // Create the request

    // Send the request
    Console.WriteLine("  Validating Saved Query");
    try
    {
        // executing the request will throw an exception if the fetch xml is invalid
