C#数组转换为指针

悬赏园豆:10 [已解决问题] 解决于 2012-06-13 15:02

谁做个C#中的数组转换成指针啊?我做得这个用fixed语句将数组转换成为指针之后为什么他的地址不是按照顺序来的呢?总共有6个数组成员,他们分别在指针的-4~1这几个地址里面了,而且顺序也变了,请问下谁知道这个怎么解决啊!在此先谢过了!

问题补充:

StructInfo.GLYDENOMINATION[] denomination = new StructInfo.GLYDENOMINATION[6];
                GLYCURRENCY ncy0 = new StructInfo.GLYCURRENCY()
                {
                    ulCounts = 1,
                    ulValue = 1,
                    Rev = 2,
                    Category = 4214
                };
                AddCurrencyID(ncy0.cCurrencyID);
                denomination[4].lpCurrencies = &ncy0;
                denomination[4].ulArraySize = 7;

                StructInfo.GLYCURRENCY ncy1 = new StructInfo.GLYCURRENCY()
                {
                    ulCounts = 1,
                    ulValue = 5,
                    Rev = 2,
                    Category = 4214
                };
                AddCurrencyID(ncy1.cCurrencyID);
                denomination[0].lpCurrencies = &ncy1;
                denomination[0].ulArraySize = 7;

                StructInfo.GLYCURRENCY ncy2 = new StructInfo.GLYCURRENCY()
                {
                    ulCounts = 1,
                    ulValue = 10,
                    Rev = 2,
                    Category = 4214
                };
                AddCurrencyID(ncy2.cCurrencyID);
                denomination[1].lpCurrencies = &ncy2;
                denomination[1].ulArraySize = 7;

                StructInfo.GLYCURRENCY ncy3 = new StructInfo.GLYCURRENCY()
                {
                    ulCounts = 1,
                    ulValue = 20,
                    Rev = 3,
                    Category = 4214
                };
                AddCurrencyID(ncy3.cCurrencyID);
                denomination[5].lpCurrencies = &ncy3;
                denomination[5].ulArraySize = 7;

                StructInfo.GLYCURRENCY ncy4 = new StructInfo.GLYCURRENCY()
                {
                    ulCounts = 1,
                    ulValue = 50,
                    Rev = 3,
                    Category = 4214
                };
                AddCurrencyID(ncy4.cCurrencyID);
                denomination[2].lpCurrencies = &ncy4;
                denomination[2].ulArraySize = 7;

                StructInfo.GLYCURRENCY ncy5 = new StructInfo.GLYCURRENCY()
                {
                    ulCounts = 1,
                    ulValue = 100,
                    Rev = 3,
                    Category = 4214
                };
                AddCurrencyID(ncy5.cCurrencyID);
                denomination[3].lpCurrencies = &ncy5;
                denomination[3].ulArraySize = 7;

 

fixed (StructInfo.GLYDENOMINATION* denomination0 = denomination)
                {
                    counter[5].Denomination = *denomination0;
                }

 

StructInfo是存放结构体的类

GLYDENOMINATION、GLYCURRENCY是结构体

AddCurrencyID()是给cCurrencyID[]赋值用的。

unsafe private static void AddCurrencyID(byte* CurrencyID)
        {
            byte[] ID = new byte[4] { 67, 78, 89, 0 };
            byte* pSrc = CurrencyID;
            fixed (byte* aa = ID)
            {
                for (int i = 0; i < ID.Length; i++)
                {
                    *(pSrc + i) = *(aa + i);
                }
            }
        }

 

public struct GLYDENOMINATION
        {
            public int ulArraySize; //lpCurrencies指向的数组大小
            unsafe public GLYCURRENCY* lpCurrencies;// GLYCURRENCY数据结构数组的指针
        }

 

public struct GLYCURRENCY
        {
            public int ulValue; 
            public int ulCounts;
            public unsafe fixed byte cCurrencyID[4];
            public int Rev; 
            public int Category;
        }

把你的代码贴出来看看,不应该出现这样的问题。

@陈世鹏: 怎么个乱法?

@笨笨蜗牛: 也没乱,就是感觉跟错位了似的,本来地址不应该是0~5来显示数据的吗,现在他是-4~1来显示数据了!

@陈世鹏: 数据正确就行。前期先满足问题的解决需求。

@笨笨蜗牛: 只是数据正确而已,他的地址不对我也用不到他的数据,我写的这个是给赋值的,不是用来接收值的,所以必须要地址完全正确才行的!
