UserControl在C＃中获取set属性

Question

I am getting an error like

"An unhandled exception of type 'System.StackOverflowException' occurred in ciscontrols.dll".

My code is given below

    private int _vin;

    public int MaxLength
    {
        get { return _vin; }

        set //Here your answer solve the promblem
        {
            txtLocl.MaxLength = value;
            if (value < 2)
            {
                throw new ArgumentOutOfRangeException("MaxLength","MaxLength MinValue should be 2.");
            }
            else this._vin = value;
        }
    }

i am creating a new property for decimal places

private int Dval;
    public int DecPlaces
    {
        get { return Dval; }
        set// here it showing the same error
        {
            DecPlaces = value; // MaxLength is a preDefined Property but  DecPlaces created by me.
            if (value < 2)
            {
                throw new ArgumentOutOfRangeException("decplaces", "decimal places minimum value should be 2.");
            }
            else this.Dval = value;
        }
    }

Answer 1

Your setter is recursive because you have

this.MaxLength = value;

Within your setter. This will result in an infinite loop, and eventually, a StackOverflowException .

Use

this._vin = value;

Instead

Answer 2

your property's setter is calling itself on this line:

 this.MaxLength = value;

Change it to:

set //Here i am getting Error
{
    txtLocl.MaxLength = value;
    if (value < 2)
    {
        throw new ArgumentOutOfRangeException("MaxLength","MaxLength MinValue should be 2.");
    }
    else this._vin = value;
}

For this particular exception, the Call Stack window displayed in Visual Studio while debugging is helpful in seeing which methods are calling each other in an infinite loop. The setter of a property eventually becomes a method called set_MaxLength in the run-time.

Answer 3

this.MaxLength = value

该行触发一个无限循环，因为它调用了您已经在其中的set访问器。您是要设置后备变量的值吗？
