BuildProvider.CodeCompilerType Property

public:
 virtual property System::Web::Compilation::CompilerType ^ CodeCompilerType { System::Web::Compilation::CompilerType ^ get(); };

public virtual System.Web.Compilation.CompilerType CodeCompilerType { get; }

member this.CodeCompilerType : System.Web.Compilation.CompilerType

Public Overridable ReadOnly Property CodeCompilerType As CompilerType

Property Value

A read-only CompilerType representing the code generator, code compiler, and compiler settings used to build source code for the virtual path. The base class returns null.

Examples

The following code example illustrates a simple build provider implementation, inheriting from the abstract BuildProvider base class. The build provider overrides the CodeCompilerType, GetGeneratedType, and GenerateCode members of the base class.

    }

    // Return the internal CompilerType member 
    // defined in this implementation.
    public override CompilerType CodeCompilerType
    {
        get { return _compilerType; }
    }

    // Define the build provider implementation of the GenerateCode method.
    public override void GenerateCode(AssemblyBuilder assemBuilder)
    {

        // the assembly builder.

        TextWriter tw = assemBuilder.CreateCodeFile(this);

                // and write it to a file specified by the assembly builder.

                provider.GenerateCodeFromCompileUnit(compileUnit, tw, null);

Remarks

Use the CodeCompilerType property to provide the settings for compiling source code for an implementation of BuildProvider. The CodeCompilerType property is null if the build provider does not require a specific code language for generating and compiling source code.

To set the value for a CompilerType object within a build provider implementation, use the GetDefaultCompilerType or GetDefaultCompilerTypeForLanguage method.

The CodeDomProviderType property specifies the CodeDomProvider implementation that is used to generate and compile source code for a build provider. The CompilerParameters property defines the settings that are used to compile the source code into an assembly.
