A decimal[,] in C# is a two-dimensional array that stores decimal values in rows and columns. Each element of the array is accessed using its row and column index. This type of array is useful for storing numeric data in a tabular format.
Code example:
Here is an example of how to declare and initialize a decimal[,] array:
This creates a 2x3 array of decimal values, and initializes the values of each element.
Another example of using a decimal[,] array is to perform mathematical operations on the elements. For example, to calculate the sum of all values in the array, you could use a nested loop to iterate over each element, and add its value to a running total.
decimal sum = 0M; for (int i = 0; i < values.GetLength(0); i++) { for (int j = 0; j < values.GetLength(1); j++) { sum += values[i,j]; } }
This code initializes a variable sum to zero, and then uses a nested loop to iterate over all elements of the array. Each element's value is added to the sum.
Package library:
The System namespace in C# provides support for working with decimal[,] arrays, and is included in the base class library. No additional package library is required.
