通过

RuntimeEnvironment 类

  • 项目

提供一个返回有关公共语言运行库环境的信息的 static 方法的集合。

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

语法

声明
<ComVisibleAttribute(True)> _
Public Class RuntimeEnvironment
用法
Dim instance As RuntimeEnvironment

[ComVisibleAttribute(true)] 
public class RuntimeEnvironment

[ComVisibleAttribute(true)] 
public ref class RuntimeEnvironment

/** @attribute ComVisibleAttribute(true) */ 
public class RuntimeEnvironment

ComVisibleAttribute(true) 
public class RuntimeEnvironment

示例

此示例演示如何调用许多由 RuntimeEnvironment 类定义的方法。

using System;
using System.Reflection;
using System.Runtime.InteropServices;

public sealed class App 
{
    static void Main() 
    {       
        // Show whether the EXE assembly was loaded from the GAC or from a private subdirectory.
        Console.WriteLine("Did the {0} assembly load from the GAC? {1}",
           Assembly.GetExecutingAssembly(),
           RuntimeEnvironment.FromGlobalAccessCache(Assembly.GetExecutingAssembly()));
        
        // Show the path where the CLR was loaded from.
        Console.WriteLine("Runtime directory: {0}", RuntimeEnvironment.GetRuntimeDirectory());

        // Show the CLR's version number.
        Console.WriteLine("System version: {0}", RuntimeEnvironment.GetSystemVersion());

        // Show the path of the machine's configuration file.
        Console.WriteLine("System configuration file: {0}", RuntimeEnvironment.SystemConfigurationFile);
    }
}

// This code produces the following output.
//
// Did the RuntimeEnvironment, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
// assembly load from the GAC? False
// Runtime directory: C:\WINDOWS\Microsoft.NET\Framework\v2.0.40607\
// System version: v2.0.40607
// System configuration file: C:\WINDOWS\Microsoft.NET\Framework\v2.0.40607\config\
// machine.config

using namespace System;
using namespace System::Reflection;
using namespace System::Runtime::InteropServices;

int main()
{
    // Show whether the EXE assembly was loaded from the GAC or from a
    // private subdirectory.
    Console::WriteLine("Did the {0} assembly load from the GAC? {1}",
        Assembly::GetExecutingAssembly(),
        RuntimeEnvironment::FromGlobalAccessCache(
        Assembly::GetExecutingAssembly()));

    // Show the path where the CLR was loaded from.
    Console::WriteLine("Runtime directory: {0}",
        RuntimeEnvironment::GetRuntimeDirectory());

    // Show the CLR's version number.
    Console::WriteLine("System version: {0}",
        RuntimeEnvironment::GetSystemVersion());

    // Show the path of the machine's configuration file.
    Console::WriteLine("System configuration file: {0}",
        RuntimeEnvironment::SystemConfigurationFile);
}

// This code produces the following output.
//
// Did the RuntimeEnvironment, Version=0.0.0.0, Culture=neutral,
// PublicKeyToken=null
// assembly load from the GAC? False
// Runtime directory: C:\WINDOWS\Microsoft.NET\Framework\v2.0.40607\
// System version: v2.0.40607
// System configuration file:
// C:\WINDOWS\Microsoft.NET\Framework\v2.0.40607\config\machine.config
