C# Addition of two 2-Dimensional Arrays
提问by LostStudent
Okay, So as the title says I need help finding a simple way of adding two arrays together. This is my code so far:
好的，正如标题所说，我需要帮助找到一种将两个数组相加的简单方法。到目前为止，这是我的代码：
static void Main()
{
Console.Write("Enter Rows: ");
int row = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter Columns: ");
int col = Convert.ToInt32(Console.ReadLine());
int[,] a = new int[row, col];
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
Console.Write("Enter Matrix({0},{1}): ", i, j);
a[i, j] = Convert.ToInt32(Console.ReadLine());
}
}
int[,] b = new int[row, col];
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
Console.Write("Enter Matrix({0},{1}): ", i, j);
a[i, j] = Convert.ToInt32(Console.ReadLine());
}
}
So, how would I add these two array together, and print out the result. Thanks.
那么，我如何将这两个数组相加，并打印出结果。谢谢。

static void Main()
{
// Your code
int[,] result = new int[row, col];
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
result [i, j] = a[i,j] + b[i,j];
Console.Write(result[i, j] + " ");
}
Console.WriteLine();
}
}

After summing both arrays you need to go for a new for loop to print the new array
对两个数组求和后，您需要使用新的 for 循环来打印新数组
// your code
int[,] result = new int[row, col];
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
result[i, j] = a[i, j] + b[i, j];
}
}
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
Console.Write(result[i, j] + " ");
}
Console.WriteLine();
}
