使用二维数组变量在switch语句C＃错误 [英] C# error in switch statement using an 2d array variable

问题描述

如果有一个值赋给（阵列）的问题在switch语句变量。

If have a problem to assign a value to a (array) variable in a switch statement.

我有使用类似myArrayTemp1和myArrayTemp2TEMP变量有效的解决方案。
但是我不知道为什么我不能使用下面的code。

I have a solution that works using "Temp" variables like myArrayTemp1 and myArrayTemp2. However I wonder why I can not use the following code.

我不知道，如果这事做与变量的范围......所以这里是我的code：

I'm not sure if this has something to do with the scope of the variable...so here is my code :

    int x;
    x=1;


        string[,] myArray = new string[2, 2]; 


        switch (x)
        {
            case 1:
                string[,] myArrayTemp1 = { { "1", "1" }, { "1", "1" } };  //is OK
                myArray = myArrayTemp1;                                   //is OK

                myArray =  { { "1", "1" }, { "1", "1" } };                //error
                break;

            case 2:
                string[,] myArrayTemp2 = { { "2", "2" }, { "2", "2" } }; //is OK
                myArray = myArrayTemp2;                                  //is OK

                myArray =  { { "2", "2" }, { "2", "2" } };                //error
                break;

        }

MessageBox.Show ("myArray:" + myArray[0,0]);

我想摆脱myArrayTemp1和myArrayTemp2和分配值的情况下块MYARRAY。
我需要使用myArray的= {{1，1}，{1，1}};符号和不myArray的[X，Y] =1

I want to get rid of myArrayTemp1 and myArrayTemp2 and assign values to myArray in the case blocks. And I need to use the myArray = { { "1", "1" }, { "1", "1" } }; notation and not myArray[x,y] = "1"

感谢您

推荐答案

您只需要创建新的数组：

You just need to create the new array:

string[,] myArray = new string[2, 2];
...
myArray =  new string[2,2] { { "1", "1" }, { "1", "1" } };
