[英]Stack Overflow in C#
I have this register that registers all the objects I need: 我有这个寄存器来注册我需要的所有对象:
public static class ObjectRegister
{
public static List<IObject> RegisteredObjects = new List<IObject>();
static ObjectRegister()
{
RegisteredObjects.Add(new Object1());
RegisteredObjects.Add(new Object2());
RegisteredObjects.Add(new Object3());
}
}
Next I have this function that checks a list and if the items in the list pass the test, it creates an object instance and adds it to the list: 接下来,我有一个检查列表的函数,如果列表中的项目通过测试,它将创建一个对象实例并将其添加到列表中:
public static List<IObject> Scan(List<parametar> list)
{
List<IObject> neededObjects = new List<IObject>();
foreach (IObject registeredObject in ObjectRegister.RegisteredObjects)
{
foreach (parametar param in list)
{
if (registeredObject.Test(param)) //returns true or false
{
neededObjects.Add(registeredObject.CreateInstance(param));
}
}
}
return connectedObjects;
}
Here is the CreateInstace method for Object1: 这是Object1的CreateInstace方法:
public IObject CreateInstance(parametar param)
{
return new Object1(param);
}
And here is the constructor: 这是构造函数:
public Object1(parametar newParam)
{
this.param = newParam;
}
It keeps trowing StackOverflow exception on this line: 它不断在这行上引发StackOverflow异常:
this.param = newParam;
Tried all the possibilities for creating an instance, default constructor, empty object etc etc, but nothing worked... any ideas? 尝试了创建实例,默认构造函数,空对象等的所有可能性,但是没有任何效果……有什么想法吗?
Thanx 谢谢
EDIT: Code to the Object1 class: 编辑:编码到Object1类:
public class Object1: IObject
{
public parametar param
{
get { return this.param; }
set { this.param = value; }
}
internal Object1() { }
public Object1(parametar newParam)
{
this.param = newParam;
}
public bool test(parametar param)
{
// I do the propper checking of the param here, and return the result
}
public IObject CreateInstance(parametar param)
{
return new Object1(param);
}
}
This is your problem, in Object1: 这是您在Object1中遇到的问题:
public parametar param { get { return this.param; } set { this.param = value; }
That property calls itself recursively - which is exactly why you're getting a stack overflow. 该属性以递归方式调用自身-这正是为什么会出现堆栈溢出的原因。 Don't do that.
不要那样做 Instead, you probably either want an automatically-implemented property:
相反,你可能要么需要一个自动实现的属性:
public parameter param { get; set; }
or use a private backing field: 或使用私人支持字段:
private parametar param;
public parametar Param { get { return param; } set { param = value; }
Additionally, I'd strongly recommend that you start following .NET naming conventions , and pay attention to spelling in type and member names. 另外,我强烈建议您开始遵循.NET命名约定 ,并注意类型和成员名称的拼写。
So you probably want your class to be called Parameter
- although personally I'd at least try to make it a little bit more descriptive, eg QueryParameter
or something similar. 因此,您可能希望将您的类称为
Parameter
尽管就我个人而言,我至少会尝试使其更具描述性,例如QueryParameter
或类似名称。 Likewise Object1
isn't exactly a semantically-meaningful name - I hope it's not the name in your real code. 同样,
Object1
也不是一个语义上有意义的名称-我希望它不是您实际代码中的名称。
