ServiceBehaviorAttribute.TransactionTimeout 属性
定义
获取或设置事务必须在此期间完成的时间段。Gets or sets the period within which a transaction must complete.
public:
property System::String ^ TransactionTimeout { System::String ^ get(); void set(System::String ^ value); };
public string TransactionTimeout { get; set; }
member this.TransactionTimeout : string with get, set
Public Property TransactionTimeout As String
属性值
一个 TimeSpan 对象,表示一个时间段,事务必须在此期间完成,否则会自动中止。A TimeSpan object that represents the time within which transactions must complete or be automatically aborted.
例外
该值为 Null。The value is null.
示例
下面的配置文件指定事务超时期限为 3 分钟。The following configuration file specifies a transaction timeout period of three minutes.

using System.ServiceModel;
using System.Transactions;

// Note: To use the TransactionIsolationLevel property, you
// must add a reference to the System.Transactions.dll assembly.
/* The following service implementation:
* -- Processes messages on one thread at a time
* -- Creates one service object per session
* -- Does not release the service object when the transaction commits
* -- The isolation level is read committed.
* -- The transaction timeout is set to 3 minutes.

注解
此值设置 ChannelDispatcher.TransactionTimeout 属性。This value sets the ChannelDispatcher.TransactionTimeout property. 你还可以使用应用程序配置文件中的 < serviceTimeouts > 元素来设置此属性。You can also set this property using the <serviceTimeouts> element in an application configuration file.
