The CodeGotoStatement type exposes the following members.

  Name Description

  Name Description
Public property EndDirectives Gets a CodeDirectiveCollection object that contains end directives. (Inherited from CodeStatement.)
Public property Label Gets or sets the name of the label at which to continue program execution.
Public property LinePragma Gets or sets the line on which the code statement occurs. (Inherited from CodeStatement.)
Public property StartDirectives Gets a CodeDirectiveCollection object that contains start directives. (Inherited from CodeStatement.)
Public property UserData Gets the user-definable data for the current object. (Inherited from CodeObject.)

  Name Description
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

CodeGotoStatement can be used to represent a goto statement, which is used in some languages to redirect program flow to a specified label.

The Label property indicates the name of the label at which to continue program execution.

Note Note

Not all languages support goto statements. Call the Supports method with the GotoStatements flag to determine whether a code generator supports goto statements.

The following example code demonstrates use of a CodeGotoStatement and a CodeLabeledStatement to redirect program flow.


// Declares a type to contain the example code.
CodeTypeDeclaration type1 = new CodeTypeDeclaration("Type1");            
// Declares an entry point method.
CodeEntryPointMethod entry1 = new CodeEntryPointMethod();                        
type1.Members.Add( entry1 );
// Adds a goto statement to continue program flow at the "JumpToLabel" label.
CodeGotoStatement goto1 = new CodeGotoStatement("JumpToLabel");
entry1.Statements.Add( goto1 );
// Invokes Console.WriteLine to print "Test Output", which is skipped by the goto statement.
CodeMethodInvokeExpression method1 = new CodeMethodInvokeExpression(
    new CodeTypeReferenceExpression("System.Console"), "WriteLine", new CodePrimitiveExpression("Test Output."));
entry1.Statements.Add( method1 );
// Declares a label named "JumpToLabel" associated with a method to output a test string using Console.WriteLine.
CodeMethodInvokeExpression method2 = new CodeMethodInvokeExpression(
    new CodeTypeReferenceExpression("System.Console"), "WriteLine", new CodePrimitiveExpression("Output from labeled statement."));
CodeLabeledStatement label1 = new CodeLabeledStatement("JumpToLabel", new CodeExpressionStatement(method2) );
entry1.Statements.Add( label1 );

// A C# code generator produces the following source code for the preceeding example code:

//    public class Type1 
//    {
//        
//        public static void Main() 
//        {
//            goto JumpToLabel;
//            System.Console.WriteLine("Test Output");
//            JumpToLabel:
//            System.Console.WriteLine("Output from labeled statement.");
//        }
//    }
