CodeCompileUnit Class
Provides a container for a CodeDOM program graph.
Assembly: System (in System.dll)
CodeCompileUnit provides a container for a CodeDOM program graph.
CodeCompileUnit contains a collection that can store CodeNamespace objects containing CodeDOM source code graphs, along with a collection of assemblies referenced by the project, and a collection of attributes for the project assembly.
A CodeCompileUnit can be passed to the GenerateCodeFromCompileUnit method of an ICodeGenerator implementation along with other parameters to generate code based on the program graph contained by the compile unit.
Note: |
|---|
Some languages support only a single namespace that contains a single class in a compile unit. |
The following code example constructs a CodeCompileUnit that models the program structure of a simple "Hello World" program. This code example is part of a larger example that also produces code from this model, and is provided for the CodeDomProvider class.
' Build a Hello World program graph using ' System.CodeDom types. Public Shared Function BuildHelloWorldGraph() As CodeCompileUnit ' Create a new CodeCompileUnit to contain ' the program graph. Dim compileUnit As New CodeCompileUnit() ' Declare a new namespace called Samples. Dim samples As New CodeNamespace("Samples") ' Add the new namespace to the compile unit. compileUnit.Namespaces.Add(samples) ' Add the new namespace import for the System namespace. samples.Imports.Add(New CodeNamespaceImport("System")) ' Declare a new type called Class1. Dim class1 As New CodeTypeDeclaration("Class1") ' Add the new type to the namespace type collection. samples.Types.Add(class1) ' Declare a new code entry point method. Dim start As New CodeEntryPointMethod() ' Create a type reference for the System.Console class. Dim csSystemConsoleType As New CodeTypeReferenceExpression( _ "System.Console") ' Build a Console.WriteLine statement. Dim cs1 As New CodeMethodInvokeExpression( _ csSystemConsoleType, "WriteLine", _ New CodePrimitiveExpression("Hello World!")) ' Add the WriteLine call to the statement collection. start.Statements.Add(cs1) ' Build another Console.WriteLine statement. Dim cs2 As New CodeMethodInvokeExpression( _ csSystemConsoleType, "WriteLine", _ New CodePrimitiveExpression("Press the Enter key to continue.")) ' Add the WriteLine call to the statement collection. start.Statements.Add(cs2) ' Build a call to System.Console.ReadLine. Dim csReadLine As New CodeMethodInvokeExpression( _ csSystemConsoleType, "ReadLine") ' Add the ReadLine statement. start.Statements.Add(csReadLine) ' Add the code entry point method to ' the Members collection of the type. class1.Members.Add(start) Return compileUnit End Function
