Type.AssemblyQualifiedName 属性

定义

获取类型的程序集限定名,其中包括从中加载 Type 的程序集的名称。

public:
 abstract property System::String ^ AssemblyQualifiedName { System::String ^ get(); };
public abstract string AssemblyQualifiedName { get; }
public abstract string? AssemblyQualifiedName { get; }
member this.AssemblyQualifiedName : string
Public MustOverride ReadOnly Property AssemblyQualifiedName As String

属性值

Type 的程序集限定名,其中包括从中加载 Type 的程序集的名称;或者为 null(如果当前实例表示泛型类型参数)。

实现

示例

以下示例显示与 类关联的程序集名称和类型的完全限定名称。

using namespace System;
using namespace System::Reflection;
int main()
{
   Type^ objType = System::Array::typeid;
   
   // Print the full assembly name.
   Console::WriteLine( "Full assembly name: {0}.", objType->Assembly->FullName );
   
   // Print the qualified assembly name.
   Console::WriteLine( "Qualified assembly name: {0}.", objType->AssemblyQualifiedName );
}
// The example displays the following output if run under the .NET Framework 4.5:
//    Full assembly name:
//       mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.
//    Qualified assembly name:
//       System.Array, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.
using System;

class MyAssemblyClass
{
    public static void Main()
    {
        Type objType = typeof(Array);

        // Print the assembly full name.
        Console.WriteLine($"Assembly full name:\n   {objType.Assembly.FullName}.");

        // Print the assembly qualified name.
        Console.WriteLine($"Assembly qualified name:\n   {objType.AssemblyQualifiedName}.");
    }
}
// The example displays the following output if run under the .NET Framework 4.5:

open System

let objType = typeof<Array>

// Print the assembly full name.
printfn $"Assembly full name:\n   {objType.Assembly.FullName}."

// Print the assembly qualified name.
printfn $"Assembly qualified name:\n   {objType.AssemblyQualifiedName}."
// The example displays the following output if run under the .NET Framework 4.5:

//    Assembly qualified name:
//       System.Array, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.
Class Example
    Public Shared Sub Main()
        Dim objType As Type = GetType(Array)

        ' Display the assembly full name.
        Console.WriteLine($"Assembly full name:{vbCrLf}   {objType.Assembly.FullName}.")

        ' Display the assembly qualified name.
        Console.WriteLine($"Assembly qualified name:{vbCrLf}   {objType.AssemblyQualifiedName}.")
    End Sub
End Class
' The example displays the following output if run under the .NET Framework 4.5:

注解

类型的程序集限定名称由类型名称(包括其命名空间)组成,后跟逗号,后跟程序集的显示名称。 程序集的显示名称是使用 Assembly.FullName 属性获取的。

注意

处理器体系结构是程序集标识的一部分,可以指定为程序集名称字符串的一部分。 例如,“ProcessorArchitecture=msil”。 但是,出于兼容性原因,它不包括在 属性返回 AssemblyQualifiedName 的字符串中。 请参阅 AssemblyName.ProcessorArchitecture

所有支持公共语言运行时的编译器都会发出嵌套类的简单名称,反射会在查询时根据以下约定构造一个错误名称。

分隔符 含义
反斜杠 (\) 转义字符。
逗号 (,) 在程序集名称之前。
加号 (+) 在嵌套类之前。
句点 (.) 表示命名空间标识符。
括号 ([]) 在类型名称之后,表示该类型的数组。



对于泛型类型,将泛型类型参数列表括起来。



在类型参数列表中,将程序集限定的类型括起来。

例如,类的程序集限定名称可能如下所示:

TopNamespace.SubNameSpace.ContainingClass+NestedClass, MyAssembly, Version=1.3.0.0, Culture=neutral, PublicKeyToken=b17a5c561934e089

如果命名空间包含加号(例如 TopNamespace.Sub+Namespace),则加号 (+) 前面将带有转义字符 (\) ,以防止将其解释为嵌套分隔符。 反射将发出此字符串,如下所示:

TopNamespace.Sub\+Namespace.ContainingClass+NestedClass, MyAssembly, Version=1.3.0.0, Culture=neutral, PublicKeyToken=b17a5c561934e089

“++”变为“\+\+”,“\”变为“\\”。

此限定名称可以持久保存,稍后用于加载 Type。 若要搜索并加载 Type,请 GetType 仅使用类型名称或程序集限定类型名称。 GetType 仅具有类型名称的 将在调用方程序集中查找 Type ,然后在系统程序集中查找 。 GetType 具有程序集限定的类型名称将在任何程序集中查找 Type

类型名称可能包含尾随字符,这些字符表示有关该类型的其他信息,例如类型是引用类型、指针类型还是数组类型。 若要检索没有这些尾随字符的类型名称,请使用 t.GetElementType().ToString(),其中 t 是 类型。

除程序集名称之外,空格与所有类型名称组件相关。 在程序集名称中,“,”分隔符前的空格是相关的,但“,”分隔符后面的空格将被忽略。

泛型类型的泛型参数本身由程序集名称限定。 例如,在 Visual Basic) 中 (MyGenericClass(Of Integer) 的程序集限定类型名称MyGenericClass<int>中,int将展开为 的Int32程序集限定类型名称。

如果当前 Type 对象表示泛型参数,则此属性返回 null
