CodeGotoStatement Class

Represents a goto statement.

Namespace:  System.CodeDom
Assembly:  System (in System.dll)

public class CodeGotoStatement : CodeStatement

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.


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.");
//        } 
//    }

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
