일부 텍스트의 내용을 XML 파일로 serialize (사용자가 선택 항목을 저장할 때 수행됨) 한 다음 나중에 사용자가 선택한 선택 사항을 표시하도록 선택하면 해당 내용이 deserialize됩니다.XML로 직렬화 할 수 없습니다.
다음은 tutorial의 직렬화입니다.
LINQ to XML을 통해이 작업을 시도했지만 네임 스페이스 오류가 발생했거나 도구가 오류를 반환하지는 않았지만 작동하지 않았습니다 (아래에서 설명하는 것과 동일한 문제가 있음).
문제는 내 코드가 오류를 반환하지 않지만 함수가 작동하지 않는다는 것입니다. 즉, 'catch'가 반환된다는 것을 알 수있는 레이블 컨트롤이 있습니다. Expression Blend에서 C#을 사용하여 도구를 작성합니다. 여기

TextWriter textWriter = new StreamWriter(@"/SavedSelections.xml");
serializer.Serialize(textWriter, selection);
textWriter.Close();
}
내 C# 코드 내 SaveSelection.cs 클래스 I 시도했다.
제 문제는이 도구를 사용하려고 할 때 SelectionLabel.Text가 "선택 항목을 저장하는 중에 문제가 발생했습니다. 잠시 후 다시 시도하십시오." 그래서 나는 코드가 catch를 반환하고 'try'를 실행하지 않는다는 것을 안다.
어떤 도움 ??
