打开/关闭Web服务

本文关键字：服务 Web 关闭 打开 | 更新日期: 2023-09-27 18:14:56

我有一个服务。我们正在向这个服务发送记录。但是，当我们发送太多记录(3000条)时，服务会超时。我的想法是将记录分解并打开服务，然后每1000条记录关闭一次。

然而，我得到一个错误:

{"Cannot access a disposed object.'r'nObject name: 'System.ServiceModel.Channels.ServiceChannel'."}
下面是我的代码: 
ServiceClient client = new ServiceClient();
foreach (Record rc in creditTransactionList)
{
    //if we are not on the last one...
    if (currentTransCount < totalTransCount)
    {
        //Current batch count is less than 1,000
        if (currentBatchCount <= amountPerBatch)
        {
            currentBatchCount++;
            if (rc != null)
                client.RecordInsert(rc);
        }
        //Current batch count is 1,000
        if (currentBatchCount == amountPerBatch)
        {
            currentBatchCount = 0;
            client.Close();
            client.Open();
        }
        //Increment Total Counter by 1
        currentTransCount++;
    }
    else
    {
        currentBatchCount++;
        if (rc != null)
            client.RecordInsert(rc);
        client.Close();
    }
}
amountPerBatch = 1000;
totalTransCount = ACHTransactionList.Count();
currentBatchCount = 0;
currentTransCount = 1;
foreach (Record rc in ACHTransactionList)
{
    //if we are not on the last one...
    if (currentTransCount < totalTransCount)
    {
        //Current batch count is less than 1,000
        if (currentBatchCount <= amountPerBatch)
        {
            currentBatchCount++;
            if (rc != null)
                client.RecordInsert(rc);
        }
        //Current batch count is 1,000
        if (currentBatchCount == amountPerBatch)
        {
            currentBatchCount = 0;
            client.Close();
            client.Open();
        }
        //Increment Total Counter by 1
        currentTransCount++;
    }
    else
    {
        currentBatchCount++;
        if (rc != null)
            client.RecordInsert(rc);
        client.Close();
    }
}
我创建了一个示例控制台应用程序来执行此操作，但是当我实际将它与实际服务合并到实际项目中时，我得到了一个错误。你能帮我弄清楚我做错了什么吗?必须是我的客户。打开和客户端。我猜差不多。任何帮助都非常感谢!!

打开/关闭Web服务

我会尝试这样做…注意，您也应该始终对客户机进行.Dispose()。此外，如果发生错误，则.Close()不再在客户端上工作，而必须.Abort()它。

ServiceClient client = new ServiceClient();
try
{
  foreach(...)
  {
    ...
    //Current batch count is 1,000
    if (currentBatchCount == amountPerBatch)
    {
        currentBatchCount = 0;
        client.Close();
        client = new ServiceClient();
    }
    ...
  }
}
finally
{
  if(client.State == CommunicationState.Faulted)
    client.Abort();
  else
    client.Close();
}

client.Close将处置该对象。client.Open之后总是抛出错误。您需要使用new ServiceClient();

初始化客户端

我所做的是检查客户端的状态并在必要时重置它:

if (wsClient.State.Equals(CommunicationState.Faulted) || wsClient.State.Equals(CommunicationState.Closed) || wsClient.State.Equals(CommunicationState.Closing))
                {
                    wsClient = new ServiceClient();
                }
