多线程：无法调用UccContext.AddNamedProperty？ [英] multi-thread :Can't call UccContext.AddNamedProperty ?

问题描述

问题：无法在子线程中调用UccContext.AddNamedProperty。
环境：XP sp2，.NET 3.5，uccapi 2.0，C＃

我想创建一个UccContext并添加一些它上面的属性，所以我写了下面的代码：

----------------------------- CODE BEGIN --- --------------------------
UccContext m_ctx;

m_ctx = new UccContextClass（）;
m_ctx。 AddNamedProperty（"testkey"，"testvalue"）;
----------------------------- CODE END --- --------------------------

代码在主线程中运行得非常好（例如在Form1（）中）但是当我在另一个线程中编写相同的代码时，它会抛出一个访问冲突异常。
------------------------- ---- CODE BEGIN -----------------------------
public Form1（）
{
。 ..
m_EngineThread = new Thread（CommandEngine.StartThread）;
m_EngineThread.Start（）;





public static void StartThread（）
{
int iRet;
串SRET;点击UccContext m_uc;搜索结果...结果m_uc =新UccContextClass（）;点击m_uc.AddNamedProperty（"什么"，" someValue中"）; < ----抛出异常

....
}
------------------------- ---- CODE END -----------------------------

AddNamedProperty的参数不是例外原因。我试过跟随代码，它仍然抛出异常：

m_uc = new UccContextClass（）;
iRet = m_uc.Count; < ---抛出异常


为什么它如此奇怪？有人有什么建议吗？

Problem:Can't call UccContext.AddNamedProperty in sub-thread.
Environment: XP sp2,.NET 3.5,uccapi 2.0,C#

I wanna create a UccContext and add some property on it, so i wrote following code:

----------------------------- CODE BEGIN -----------------------------
UccContext m_ctx;

m_ctx = new UccContextClass();
m_ctx.AddNamedProperty("testkey","testvalue");
----------------------------- CODE END    -----------------------------

the code works very well when they are in main thread(e.g. in Form1()).
But when i wrote the same code in another thread, it throw a access violation exception.
----------------------------- CODE BEGIN -----------------------------
  public Form1()
  {
   ...
   m_EngineThread = new Thread(CommandEngine.StartThread);
   m_EngineThread.Start();
   ...
  }

  public static void StartThread()
  {
            int iRet;
            string sRet;
            UccContext   m_uc;
   
           ...
           m_uc = new UccContextClass();
           m_uc.AddNamedProperty("something","somevalue");  <---- throw exception

           ....
  }
----------------------------- CODE END    -----------------------------

the parameters of AddNamedProperty is not the exception reason.
I tried follow codes, it still throw exception:

           m_uc = new UccContextClass();
           iRet = m_uc.Count;  <--- throw exception


why it's so strange? Anyone has some suggestions?
