예제

다음 예제 코드는 예외 처리를 위한 문을 정의하는 try...catch...finally 데 사용하는 CodeTryCatchFinallyStatement 방법을 보여 줍니다.

// Declares a type to contain a try...catch block.
CodeTypeDeclaration type1 = new CodeTypeDeclaration("TryCatchTest");

// Defines a method that throws an exception of type System.ApplicationException.
CodeMemberMethod method1 = new CodeMemberMethod();
method1.Name = "ThrowApplicationException";
method1.Statements.Add( new CodeThrowExceptionStatement(
    new CodeObjectCreateExpression("System.ApplicationException", new CodePrimitiveExpression("Test Application Exception")) ) );
type1.Members.Add( method1 );

// Defines a constructor that calls the ThrowApplicationException method from a try block.
CodeConstructor constructor1 = new CodeConstructor();
constructor1.Attributes = MemberAttributes.Public;
type1.Members.Add( constructor1 );

// Defines a try statement that calls the ThrowApplicationException method.
CodeTryCatchFinallyStatement try1 = new CodeTryCatchFinallyStatement();
try1.TryStatements.Add( new CodeMethodInvokeExpression( new CodeThisReferenceExpression(), "ThrowApplicationException" ) );
constructor1.Statements.Add( try1 );

// Defines a catch clause for exceptions of type ApplicationException.
CodeCatchClause catch1 = new CodeCatchClause("ex", new CodeTypeReference("System.ApplicationException"));
catch1.Statements.Add( new CodeCommentStatement("Handle any System.ApplicationException here.") );
try1.CatchClauses.Add( catch1 );

// Defines a catch clause for any remaining unhandled exception types.
CodeCatchClause catch2 = new CodeCatchClause("ex");
catch2.Statements.Add( new CodeCommentStatement("Handle any other exception type here.") );
try1.CatchClauses.Add( catch2 );

// Defines a finally block by adding to the FinallyStatements collection.
try1.FinallyStatements.Add( new CodeCommentStatement("Handle any finally block statements.") );

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

//    public class TryCatchTest
//    {
//
//        public TryCatchTest()
//        {
//            try
//            {
//                this.ThrowApplicationException();
//            }
//            catch (System.ApplicationException ex)
//            {
//                // Handle any System.ApplicationException here.
//            }
//            catch (System.Exception ex)
//            {
//                // Handle any other exception type here.
//            }
//          finally {
//                // Handle any finally block statements.
//            }
//        }
//
//        private void ThrowApplicationException()
//        {
//            throw new System.ApplicationException("Test Application Exception");
//        }
//    }

설명

CodeTryCatchFinallyStatement 는 코드 블록을 나타내는 try/catch 데 사용할 수 있습니다.

속성에는 TryStatements 블록 내에서 try 실행할 문이 포함됩니다. 속성에는 CatchClauses catch된 catch 예외를 처리하는 절이 포함되어 있습니다. 속성에는 FinallyStatements 블록 내에서 finally 실행할 문이 포함됩니다.

메모

모든 언어가 블록을 지원하는 try/catch 것은 아닙니다. 플래그를 Supports 사용하여 메서드를 GeneratorSupport.TryCatchStatements 호출하여 코드 생성기가 블록을 지원하는지 여부를 확인합니다/trycatch.
