结构体里面有object[]，两难问题

Question

   public struct strColumnStyleSet
        {
            public strColumnStyleSet(int _iColumnSelect, string _strHeaderText, string _strName, object[] _objComboNumber)
            {
                iColumnSelect = _iColumnSelect;
                strHeaderText = _strHeaderText;
                strName = _strName;
                _objComboNumber = objComboNumber;
            }            public int iColumnSelect;
            public string strHeaderText;
            public string strName;
            public object[] objComboNumber;            public int _iColumnSelect
            {
                get
                {
                    return iColumnSelect;
                }
                set
                {
                    iColumnSelect = value;
                }
            }            public string _strHeaderText
            {
                get
                {
                    return strHeaderText;
                }
                set
                {
                    strHeaderText = value;
                }
            }            public string _strName
            {
                get
                {
                    return strName;
                }
                set
                {
                    strName = value;
                }
            }
        }
结构体里面没办法对public object[] objComboNumber;赋予初值。
但是如果我不赋予初值，又在构造函数public strColumnStyleSet(int _iColumnSelect, string _strHeaderText, string _strName, object[] _objComboNumber)中告诉我必须执行这个栏位，两难啊，请教！！！

又在构造函数public strColumnStyleSet(int _iColumnSelect, string _strHeaderText, string _strName, object[] _objComboNumber)中告诉我必须指定这个栏位，两难啊，请教！！！

Answer 2

你的用法比较奇怪。如果objComboNumber 类型可变，开始定义成模板类吧
另外这样写错了
objComboNumber = _objComboNumber;

Answer 3

public strColumnStyleSet(int _iColumnSelect, string _strHeaderText, string _strName, 
object[]  _objComboNumber = null)给他默认成null 不行么

Answer 4

参考用法    public struct strColumnStyleSet<T>
    {
        public strColumnStyleSet(int _iColumnSelect, string _strHeaderText, string _strName, T[] _objComboNumber)
        {
            iColumnSelect = _iColumnSelect;
            strHeaderText = _strHeaderText;
            strName = _strName;
            objComboNumber = _objComboNumber;
        }        public int iColumnSelect;
        public string strHeaderText;
        public string strName;
        public T[] objComboNumber;        public int _iColumnSelect
        {
            get
            {
                return iColumnSelect;
            }
            set
            {
                iColumnSelect = value;
            }
        }        public string _strHeaderText
        {
            get
            {
                return strHeaderText;
            }
            set
            {
                strHeaderText = value;
            }
        }        public string _strName
        {
            get
            {
                return strName;
            }
            set
            {
                strName = value;
            }
        }
    }
        // 调用
        private void btnResultSel_Click(object sender, EventArgs e)
        {
            int[] arr = new int[2];
            arr[0] = 1;
            arr[1] = 101;
            strColumnStyleSet<int> aa = new strColumnStyleSet<int>(1, "gogo", "comeon", arr);
        }

Answer 5

你可以采用变参方式：声明如下params可变参数，然后用for循环给object[]赋值
public static void UseParams2(params object[] list) 
    {
        for (int i = 0 ; i < list.Length; i++)
        {
            Console.WriteLine(list[i]);
        }
        Console.WriteLine();
    }

Answer 6

你的结构成员又有string又有object[]，显然已经违反了结构设计原则...除非用于与非托管程序的交互参数，否则你根本就不应该用结构...
