CompilerInfo.CodeDomProviderType 屬性

定義

命名空間:

System.CodeDom.Compiler

組件:

System.CodeDom.dll

套件:

System.CodeDom v8.0.0

來源:

CompilerInfo.cs

取得已設定 CodeDomProvider 之實作的類型。

public:
 property Type ^ CodeDomProviderType { Type ^ get(); };

public Type CodeDomProviderType { get; }

member this.CodeDomProviderType : Type

Public ReadOnly Property CodeDomProviderType As Type

屬性值

Type

表示已設定之語言提供者類型的唯讀 Type 執行個體。

例外狀況

ConfigurationException

在這部電腦上未設定此語言提供者。

ConfigurationErrorsException

找不到型別，因為該型別為 null 或空字串。

-或-

找不到型別，因為在組態檔中找不到 CodeDomProvider 的名稱。

範例

下列程式代碼範例會判斷輸入語言是否在計算機上具有已設定 CodeDomProvider 的實作。 如果有針對指定語言設定的提供者，此範例會顯示語言提供者組態設定。 此程式代碼範例是針對 類別提供的較大範例的 CompilerInfo 一部分。

CodeDomProvider^ provider = nullptr;
CompilerInfo^ info = CodeDomProvider::GetCompilerInfo( configLanguage );

// Check whether there is a provider configured for this language.
if ( info->IsCodeDomProviderTypeValid )
{
   // Get a provider instance using the configured type information.
   provider = dynamic_cast<CodeDomProvider^>(Activator::CreateInstance( info->CodeDomProviderType ));
   if ( provider )
   {
      // Display information about this language provider.
      Console::WriteLine( "Language provider:  {0}", provider->ToString() );
      Console::WriteLine();
      Console::WriteLine( "  Default file extension:  {0}", provider->FileExtension );
      Console::WriteLine();
      
      // Get the compiler settings for this language.
      CompilerParameters^ langCompilerConfig = info->CreateDefaultCompilerParameters();
      if ( langCompilerConfig )
      {
         Console::WriteLine( "  Compiler options:        {0}", langCompilerConfig->CompilerOptions );
         Console::WriteLine( "  Compiler warning level:  {0}", langCompilerConfig->WarningLevel.ToString() );
      }
   }
}

if ( provider == nullptr ) // Tell the user that the language provider was not found.
   Console::WriteLine( "There is no provider configured for input language \"{0}\".", configLanguage );

CompilerInfo info = CodeDomProvider.GetCompilerInfo(configLanguage);

// Check whether there is a provider configured for this language.
if (info.IsCodeDomProviderTypeValid)
{

    CodeDomProvider provider;
    provider = (CodeDomProvider)Activator.CreateInstance(info.CodeDomProviderType);

    // Display information about this language provider.

        provider.ToString());
    Console.WriteLine();
    Console.WriteLine("  Default file extension:  {0}",
        provider.FileExtension);
    Console.WriteLine();

    CompilerParameters langCompilerConfig = info.CreateDefaultCompilerParameters();

    Console.WriteLine("  Compiler options:        {0}",
        langCompilerConfig.CompilerOptions);
    Console.WriteLine("  Compiler warning level:  {0}",
        langCompilerConfig.WarningLevel);
}
else
{
    // Tell the user that the language provider was not found.
    Console.WriteLine("There is no provider configured for input language \"{0}\".",
        configLanguage);
}

Dim info As CompilerInfo = CodeDomProvider.GetCompilerInfo(configLanguage)

' Check whether there is a provider configured for this language.
If info.IsCodeDomProviderTypeValid Then
   ' Get a provider instance using the configured type information.
   Dim provider As CodeDomProvider
   provider = CType(Activator.CreateInstance(info.CodeDomProviderType), CodeDomProvider)
   
   ' Display information about this language provider.
   Console.WriteLine("Language provider:  {0}", _
       provider.ToString())
   Console.WriteLine()
   Console.WriteLine("  Default file extension:  {0}", _
       provider.FileExtension)
   Console.WriteLine()
   
   ' Get the compiler settings for this language.
   Dim langCompilerConfig As CompilerParameters = info.CreateDefaultCompilerParameters()
   
   Console.WriteLine("  Compiler options:        {0}", _
       langCompilerConfig.CompilerOptions)
   Console.WriteLine("  Compiler warning level:  {0}", _
       langCompilerConfig.WarningLevel)
Else
   ' Tell the user that the language provider was not found.
   Console.WriteLine("There is no provider configured for input language ""{0}"".", configLanguage)
End If

備註

計算機組態檔包含計算機上每個 CodeDomProvider 實作的完整類型名稱。 CodeDomProviderType屬性值是Type表示已設定語言提供者實作的實例。
