Inheritance
Action<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14>

Remarks

您可以使用 Action<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> 委托以参数形式传递方法,而无需显式声明自定义委托。You can use the Action<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> delegate to pass a method as a parameter without explicitly declaring a custom delegate. 封装的方法必须对应于由此委托定义的方法签名。The encapsulated method must correspond to the method signature that is defined by this delegate. 这意味着,封装的方法必须具有14个通过值传递给它的参数,并且不能返回值。This means that the encapsulated method must have 14 parameters that are all passed to it by value, and it must not return a value. (在C#中,该方法必须返回 void(In C#, the method must return void. 在 Visual Basic 中,它必须由 Sub...End SubIn Visual Basic, it must be defined by the SubEnd Sub construct。construct. 它也可以是返回忽略的值的方法。)通常,这种方法用于执行操作。It can also be a method that returns a value that is ignored.) Typically, such a method is used to perform an operation.

Note

若要引用具有14个参数并返回值的方法,请改用泛型 Func<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14,TResult> 委托。To reference a method that has 14 parameters and returns a value, use the generic Func<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14,TResult> delegate instead.

还可以将 Action<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> 委托与匿名方法和 lambda 表达式一起使用。You can also use the Action<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> delegate with anonymous methods and lambda expressions.
