Answer 1

public int CustomerID
{
    get { return CustomerID; }
    set { CustomerID = value; }
}

您正在递归地为自己分配值。其他属性也一样。

您需要使用其他名称定义备份字段，例如：

private int _CustomerId;
public int CustomerID
{
    get { return _CustomerID; }
    set { _CustomerID = value; }
}

甚至更好：

public int CustomerId {get; set;}

Answer 2

您的属性中有无限的递归调用Get＆amp;设置如下：

string Lname{ 
    get { return Lname; } 
    set { Lname = value; }
}

名称=值;将再次致电您的财产＆amp;试。

Answer 3

尝试以下方法：

public class Customers
{

    private int _CustomerID; 
    private string _Fname;
    private string _Lname;
    private string _Country;

    public Customers()    
    {        
        int CustomerID = 0;        
        string Fname = string.Empty;        
        string Lname = string.Empty;        
        string Country = string.Empty;    
    }    

    public int CustomerID    
    {        
        get { return _CustomerID; }        
        set { _CustomerID = value; }    
    }    

    public string Fname    
    {        
        get { return _Fname; }        
        set { _Fname = value; }
    }    

    public string Lname    
    {        
        get { return _Lname; }        
        set { _Lname = value; }    
    }    

    public string Country    
    {        
        get { return _Country; }        
        set { _Country = value; }    
    }

Answer 4


    public Customers()
    {
        int CustomerID = 0;
        string Fname = string.Empty;
        string Lname = string.Empty;
        string Country = string.Empty;
    }

    public int CustomerID { get; set; }

    public string Fname { get; set; }

    public string Lname { get; set; }

    public string Country  { get; set; }

}

System.StackOverflowException
