定义

命名空间:
System.Messaging
程序集:
System.Messaging.dll

获取或设置消息正文所包含数据的类型。Gets or sets the type of data that the message body contains.

public:

Public Property BodyType As Integer

Int32

例外

InvalidOperationException

消息队列经过筛选后忽略了 Body 属性。The message queue is filtered to ignore the Body property.

示例

下面的代码示例显示消息的属性的值 BodyType 。The following code example displays the value of a message's BodyType property.

注解

消息队列将正文内容识别为对象或序列化流。Message Queuing recognizes the body contents as an object or as a serialized stream. BodyType属性指示消息的属性中的对象的类型 Body 。The BodyType property indicates the type of the object within the Body property of the message.

在 XmlMessageFormatter 本机类型与消息体中的对象之间执行绑定。The XmlMessageFormatter performs binding between native types and the object in a message body. 如果使用，则 XmlMessageFormatter 格式化程序将 BodyType 为您设置属性。If you use the XmlMessageFormatter, the formatter sets the BodyType property for you.

其他格式化程序还可以提供绑定功能，如下面的 c # 代码中所示。Other formatters can provide binding functionality also, as shown in the following C# code.

message.Formatter = new ActiveXMessageFormatter();  
object myObject message.Body;  
if (myObject is string) {  
}  
if (myObject is int) {  
}  
if (myObject is float) {  
}
