我想证明在线程之间重用 OrganizationServiceProxy 的实例会导致问题。
此控制台应用程序在线程之间重新使用相同的 OrganizationServiceProxy 实例没有问题:
class Program
{
private static OrganizationServiceProxy Service { get; set; }
static void Main(string[] args)
{
Connect(); // Initializes Service
for (int i = 0; i < 100; i++)
{
int index = i;
Task.Run(() =>
{
for (int i2 = 0; i2 < 10; i2++)
{
try
{
Console.WriteLine("Creating" + index);
Entity record = new Entity("account");
record.Id = new Guid("4986e130-45f7-e411-9454-00155d91de01");
record["name"] = index + " - " + i2;
Service.Update(record);
Console.WriteLine("Created" + index);
}
catch (Exception e)
{ }
}
});
}
Console.ReadLine(); // the name of the record ends up as 99 - 9, which is right
}
/* Initialize Service */
private static bool Connect()
{
try
{
ClientCredentials cred = new ClientCredentials();
cred.UserName.UserName = @"r";
cred.UserName.Password = @"";
IServiceManagement<IOrganizationService> serviceManagement = ServiceConfigurationFactory.CreateManagement<IOrganizationService>(new Uri(@"/XRMServices/2011/Organization.svc"));
Service = new OrganizationServiceProxy(serviceManagement, cred);
var who = new Microsoft.Crm.Sdk.Messages.WhoAmIRequest(); // used to test the connection
var whoResponse = (Microsoft.Crm.Sdk.Messages.WhoAmIResponse)Service.Execute(who); // this fails if not connected
}
catch (Exception e)
{
Console.WriteLine("Connecting to CRM.\n" + e.Message + ((e.InnerException != null) ? "\n" + e.InnerException.Message : ""));
return false;
}
return true;
}
}
SDK 声明OrganizationServiceProxy 的任何实例成员都不能保证是线程安全的。
如何导致线程之间共享的 OrganizationServiceProxy 出现问题?
会出现什么样的问题?
