CompilerInfo.GetHashCode 方法

定义

命名空间:

System.CodeDom.Compiler

程序集:

System.CodeDom.dll

包:

System.CodeDom v8.0.0

Source:

CompilerInfo.cs

返回当前实例的哈希代码。

public:
 override int GetHashCode();

public override int GetHashCode ();

override this.GetHashCode : unit -> int

Public Overrides Function GetHashCode () As Integer

返回

Int32

当前 CompilerInfo 实例的 32 位带符号整数哈希代码，适合在哈希算法和数据结构（如哈希表）中使用。

示例

下面的代码示例创建 类的 Microsoft.VisualBasic.VBCodeProvider 实例。 该示例显示新提供程序实例的提供程序名称、哈希代码和默认文件扩展名。 此代码示例是为 CompilerInfo 类提供的一个更大示例的一部分。

         // Get the provider for Microsoft.VisualBasic
//         CodeDomProvider^ provider = CodeDomProvider.CreateProvider("VisualBasic");
         CodeDomProvider^ provider = CodeDomProvider::CreateProvider("VisualBasic");
         if ( provider ) // Display the Visual Basic language provider information.
         {
            Console::WriteLine( "Visual Basic provider is {0}", provider->ToString() );
            Console::WriteLine( "  Provider hash code:     {0}", provider->GetHashCode().ToString() );
            Console::WriteLine( "  Default file extension: {0}", provider->FileExtension );
         }

// Get the provider for Microsoft.VisualBasic
CodeDomProvider provider = CodeDomProvider.CreateProvider("VisualBasic");

// Display the Visual Basic language provider information.
Console.WriteLine("Visual Basic provider is {0}",
    provider.ToString());
Console.WriteLine("  Provider hash code:     {0}",
    provider.GetHashCode().ToString());
Console.WriteLine("  Default file extension: {0}",
    provider.FileExtension);

' Get the provider for Microsoft.VisualBasic
   Dim provider = CodeDomProvider.CreateProvider("VisualBasic")

' Display the Visual Basic language provider information.
Console.WriteLine("Visual Basic provider is {0}", _
   provider.ToString())
Console.WriteLine("  Provider hash code:     {0}", _
   provider.GetHashCode().ToString())
Console.WriteLine("  Default file extension: {0}", _
   provider.FileExtension)

注解

此方法替代 Object.GetHashCode 方法。

此方法为根据 Equals 方法视为相等的两个对象生成相同的哈希代码。
