为我提供真实代码的帮助

Help me with Homework please...

I have a question that one place randomly In any matrix lets say [3,2] and I must find and gather the values next to this place let's say for ---example--- if I go this binary matrix 

int[,] M = {{7,5,4},{9,8,7},{2,3,4}};   and I must gather the values beside [1,1] I must get 7+5+4+9+7+2+3+4=41 in this case it is easy but how I can gather in please [0,0] in this place I will got 9+8+5=22 Help me in real code please in C# 

REMEMBER THE PLACES AND THE MATRIX ALL ARE RANDOMLY (I JUST GIVEN THE REAL PLACE THAT I MUST GATHER THE VALUSE NEAR IT WHICH IS GIVEN BY THE USER)

LET'S SAY THE USER GAVE ME PLACE [0,0] I  MUST GATHER ALL VALUES NEAR [0,0] I DO NOT KNOW THE MATRIX!!!

推荐答案

If the place is named [a, b], where a and b are integer variables given by the user, then create a loop, which increments the i variable between a-1 and a+1, for example: ‘for( int i = a-1; i <= a+1; ++i)’.

放置在另一个类似的循环中，该循环会递增另一个变量- j —在 b-1 和 b + 1 之间.

Place inside another similar loop that increments another variable — j — between b-1 and b+1.

然后使用 i 和 j 从矩阵中提取值并将其加和.但是，必须排除不属于矩阵的像元，例如负数. i 和 j ，或者大于矩阵大小.您还必须排除[ a b ]单元格.这可以通过 if 轻松完成，例如:" if(i< 0)继续".

Then use i and j to extract the value from the matrix and add to the sum. However, you must exclude the cells that do not belong to the matrix, such as negative i and j, or which are greater than the matrix sizes. You must also exclude the [a, b] cell. This can be easily done with an if, for example: ‘if( i < 0) continue’.
