範例

下列程式碼說明如何從服務取得執行個體內容資訊︰The following code illustrates how to obtain instance context information from a service:

string info = "";

OperationContext operationContext = OperationContext.Current;
InstanceContext instanceContext = operationContext.InstanceContext;

info += "    " + "State: " + instanceContext.State.ToString() + "\n";
info += "    " + "ManualFlowControlLimit: " + instanceContext.ManualFlowControlLimit.ToString() + "\n";
info += "    " + "HashCode: " + instanceContext.GetHashCode().ToString() + "\n";

return info;
