I have covered everything you need to learn to work with C# Rectangular Array efficiently on your day-to-day job.

And I assure you if you watch all these short videos. You won’t need any other video/tutorial on these topics again.

❓ What Is Rectangular Array in C#?
C# rectangular array is an array of two (or more) dimensions separated by comma. You can think of a rectangular array as a table, where the first dimension is the number of rows and the second dimension is the number of columns keeping in mind that every row is the same length. Due to 2 dimensions, it’s also known as two-dimensional or 2D array.

C# Rectangular Array in Short
🔸 Declared using COMMA within the set of BRACKETS followed by the data type.
🔸 A COMMA separates each dimension.
🔸 Data is stored in a TABULAR form (fixed rows/columns) known as MATRIX.
🔸 Sometimes referred to as two-dimensional, multidimensional, or 2D array.
🔸 Use the nested for loops to iterate through the ROWS and COLUMNS of a rectangular array.

Syntax
type[,] arrayName = new type[rows, columns];
