如何解决StackOverflowException

本文关键字：StackOverflowException 解决何解决 | 更新日期: 2023-09-27 18:10:52

我试着写这个类:

public class ModelManager
{
    public OmniacareHomeProductionEntities _db;
    public CategoriaManager categoriaManager 
    { 
        get { return categoriaManager; }
        set 
        {
            if (categoriaManager == null)
            {
            categoriaManager = new CategoriaManagerImpl();
            }
        }
    }
    private static readonly log4net.ILog log = log4net.LogManager.GetLogger(typeof(ModelManager));
    public ModelManager()
    {
        _db = new OmniacareHomeProductionEntities();
    }
}

CategoriaManager是一个接口，而CategoriaManagerImpl是一个实现CategoriaManager的类。

我在这种模式下使用ModelManager类:

ModelManager modelManager = new ModelManager();
modelManager.categoriaManager.saveLocalCategory(category, true);

所以当我尝试运行这段代码时，在这一行有一个StackOverflowError

get 
{
    return categoriaManager;
}

我的错误在哪里?你能帮我吗?

如何解决StackOverflowException

你的问题明显在这里

  public CategoriaManager categoriaManager 
    { 
        get 
        {
            return categoriaManager;
        }
        set 
        {
            if (categoriaManager == null)
            {
                categoriaManager = new CategoriaManagerImpl(); //HERE !!!!!!!!!
            }
        }
    }

成员名与属性名相同，可以这样修改，例如:

    public CategoriaManager CatManager //NAME OF HE PROPERTY ISCHANGED !!!!
    { 
        get 
        {
            return categoriaManager;
        }
        set 
        {
            if (categoriaManager == null)
            {
                categoriaManager = new CategoriaManagerImpl();
            }
        }
    }

总则:

属性使用大写
字段使用小写

所以你的代码看起来像这样:

ModelManager modelManager = new ModelManager();
modelManager.CatManager.saveLocalCategory(category, true);

你应该这样修改:

private CategoriaManager _categoriaManager;
public CategoriaManager CategoriaManager 
{ 
    get { return _categoriaManager; }
    set 
    {
        if (_categoriaManager == null)
        {
            _categoriaManager = new CategoriaManagerImpl();
        }
    }
}
