我应该在SitkaSoapServiceClient上使用“使用”吗？

Question

(This relates to Microsoft's SitkaSoapService, in the service reference at https://database.windows.net/soap/v1/ )

I'm using SitkaSoapServiceClient to access my SQL Data Services database by SOAP.

Should I use a "using" statement every time I use this proxy class? Or does it do its own connection handling in a safe way internally?

Ie do I need to say:

using (SitkaSoapServiceClient proxy = GetProxy())
    proxy.Update(scope, entity);

... or is it safe to say:

GetProxy().Update(scope, entity);

[where GetProxy() returns a SitkaSoapServiceClient object.]

Answer 1

Does the proxy class code compile when wrapped in a using statement? If so, it implements IDisposable and I'd use it.

EDIT: calling Dispose() should incur little overhead if it does nothing, and if the designer of the class decides at a later date to allocate unmanaged resources you will be protected from a leak.

Answer 2

当类实现IDisposable时，应始终使用using ，因为类的作者告诉您它包含一些应释放的资源。
