[英]Using 2d array in C#
I'm getting the error: 我收到错误:
"Ambiguity between 'game.Form1.WallCheckerArray' and 'game.Form1.WallCheckerArray'"
“'game.Form1.WallCheckerArray'和'game.Form1.WallCheckerArray'之间存在歧义”
Because I use it twice. 因为我用了两次。 Why can't I use the same array name twice with different values?
为什么我不能使用相同的数组名称两次使用不同的值? My code is below.
我的代码如下。 The array exists out of cordinates.
该数组存在于cordinates之外。
my array: 我的阵列:
private int[,] WallCheckerArray = new int[28, 4];// <<----- was the problem
int[,] WallCheckerArray = {
{220,250,13,64},//1
{24,58,24,55},//2
{104,206,22,55},//3
{264,370,22,55},//4
{382,450,22,55},//5
{24,92,74,109},//6
{104,136,74,185},//7
{136,206,114,138},//8
{150,326,74,98},//9
{225,255,98,140},//10
{345,365,74,185},//11
{275,355,114,138},//12
{384,445,74,109},//13
{104,136,200,270},//14
{150,330,240,270},//15
{225,255,270,315},//16
{340,370,200,270},//17
{20,85,285,305},//18
{50,85,305,345},//19
{104,214,285,315},//20
{274,368,285,315},//21
{378,445,285,305},//22
{378,415,305,345},//23
{24,195,365,375},//24
{104,154,335,375},//25
{165,339,335,345},//26
{215,245,335,375},//27
{265,445,365,375},//28
{355,365,335,375}//29
};
int i = 0;
for( i = 0; i < 29; i++)
{
if (((x >= WallCheckerArray[i, 0] && x <= WallCheckerArray[i, 1]) && (y >= WallCheckerArray[i, 2] && y <= WallCheckerArray[i, 3])))//-----------------------------------}-
{
InsideWC();
System.Console.WriteLine(WallCheckerArray[i, 1]);
}
}
A line of code like int[,] WallCheckerArray = something
is read by the compiler as "Make a new int[,]
named WallCheckerArray. And the problem is, you do that twice in a row; you can't have two different variables with the same name. If you don't give a variable an access modifier, the C# compiler will assume you wanted it to be Private
. 一行代码如
int[,] WallCheckerArray = something
被编译器读作“Make a new int[,]
命名为WallCheckerArray。问题是,你连续两次这样做;你不能有两个不同的变量如果你没有给变量一个访问修饰符,C#编译器会认为你想要它是Private
。
To make your code work: 要使代码工作:
private int[,] WallCheckerArray = new int[28, 4];
WallCheckerArray = {
/* Your Data */
};
FYI: you can actually make your array and fill it with data in the same statement, like so: 仅供参考:您实际上可以在同一个语句中创建数组并用数据填充它,如下所示:
private int[,] WallCheckerArray = {
{220,250,13,64},
{24,58,24,55},
{104,206,22,55},
// and so on
};
This way, you don't have to worry about declaring the size of the array, it'll be handled for you. 这样,您不必担心声明数组的大小,它将为您处理。
不得不删除“private int [,] WallCheckerArray = new int [28,4];”
