Assembly.GetTypes 方法

获取此程序集中定义的类型。

**命名空间:**System.Reflection
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public Overridable Function GetTypes As Type()
用法
Dim instance As Assembly
Dim returnValue As Type()

returnValue = instance.GetTypes

public virtual Type[] GetTypes ()

public:
virtual array<Type^>^ GetTypes ()

public Type[] GetTypes ()

public function GetTypes () : Type[]

返回值

Type 类型的数组，包含此程序集中定义的所有类型的对象。

异常

异常类型	条件
TypeLoadException	该程序集包含无法加载的类型。该异常包含有关该类型的信息。

备注

返回的数组包含嵌套类型。

示例

下面的示例显示指定程序集中的类型。

Dim SampleAssembly As [Assembly]
SampleAssembly = [Assembly].LoadFrom("c:\Sample.Assembly.dll")
' Obtain a reference to a method known to exist in assembly.
Dim Method As MethodInfo = SampleAssembly.GetTypes()(0).GetMethod("Method1")
' Obtain a reference to the parameters collection of the MethodInfo instance.
Dim Params As ParameterInfo() = Method.GetParameters()
' Display information about method parameters.
' Param = sParam1
'   Type = System.String
'   Position = 0
'   Optional=False
Dim Param As ParameterInfo
For Each Param In Params
    Console.WriteLine(("Param=" + Param.Name.ToString()))
    Console.WriteLine(("  Type=" + Param.ParameterType.ToString()))
    Console.WriteLine(("  Position=" + Param.Position.ToString()))
    Console.WriteLine(("  Optional=" + Param.IsOptional.ToString()))
Next Param

.NET Framework 安全性

• ReflectionPermission  当通过类似 Type.InvokeMember 的机制以后期绑定的形式进行调用时。关联的枚举：ReflectionPermissionFlag.MemberAccess。
• ReflectionPermission  用于反射非公共可见的类型。关联的枚举：ReflectionPermissionFlag.MemberAccess、ReflectionPermissionFlag.TypeInformation
