Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets the type of the configured CodeDomProvider implementation.
public:
property Type ^ CodeDomProviderType { Type ^ get(); };public Type CodeDomProviderType { get; }member this.CodeDomProviderType : TypePublic ReadOnly Property CodeDomProviderType As TypeProperty Value
A read-only Type instance that represents the configured language provider type.
Exceptions
The language provider is not configured on this computer.
Cannot locate the type because it is a null or empty string.
-or-
Cannot locate the type because the name for the CodeDomProvider cannot be found in the configuration file.
Examples
The following code example determines whether the input language has a configured CodeDomProvider implementation on the computer. If there is a provider configured for the specified language, the example displays the language provider configuration settings. This code example is part of a larger example provided for the CompilerInfo class.
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)
{
// Get a provider instance using the configured type information.
CodeDomProvider provider;
provider = (CodeDomProvider)Activator.CreateInstance(info.CodeDomProviderType);
// 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();
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
Remarks
The machine configuration file contains the fully qualified type name for each CodeDomProvider implementation on the computer. The CodeDomProviderType property value is a Type instance that represents a configured language provider implementation.
