参数

name: String

属性的名称。 name 不能包含嵌入的 null。

attributes: PropertyAttributes

属性的特性。

callingConvention: CallingConventions

属性访问器的调用约定。

returnType: Type

属性的返回类型。

returnTypeRequiredCustomModifiers: Type[]

一个类型数组，它表示属性的返回类型所必需的自定义修饰符，如 IsConst。如果返回类型没有所需的自定义修饰符，则指定 null。

returnTypeOptionalCustomModifiers: Type[]

一个类型数组，它表示属性的返回类型的可选自定义修饰符，如 IsConst。如果返回类型没有可选的自定义修饰符，则指定 null。

parameterTypes: Type[]

属性的参数类型。

parameterTypeRequiredCustomModifiers: Type[][]

parameterTypeOptionalCustomModifiers: Type[][]

PropertyBuilder

定义的属性。

例外

ArgumentException

name 的长度为零。

ArgumentNullException

name 为 null。

- 或 -

parameterTypes 数组的任何元素都是 null。

InvalidOperationException

该类型是以前使用 CreateType() 创建的。
