Hello All,

Am not sure where and what am missing,any help much appreciated

ERROR Msg from Event Log

Service cannot be started. System.InvalidOperationException: Cannot find a formatter capable of reading this message. at System.Messaging.Message.get_Body() at CRSMessagePipeline.CRSService.processMessage() at CRSMessagePipeline.CRSService.OnStart(String[] args) at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

推荐答案

该错误消息明确指出了问题所在.您的MSMQ队列读取器未实现正确的格式化程序.对于代码而言，知道将以哪种格式读取队列对象非常重要.

以下是示例代码，根据您的数据类型实现相同的代码:

The error message clearly states the problem. Your MSMQ queue reader has not implemented the correct formatter. It is very important for the code to know in which format will the queue object be read.

Below is the sample code, implement the same as per your data type:

MessageQueue queue = new MessageQueue(@".\MyQueue");
System.Messaging.Message msg = new System.Messaging.Message();
msg = queue.Receive();
msg.Formatter = new System.Messaging.XmlMessageFormatter(new String[] { "System.String,mscorlib" });

希望有帮助.

Hope that helps.
