To find the number of dimensions of an array, use the Rank property.arr.RankHere, arr is our array −int[, ] arr = new int[3, 4];If you also want to get the rows and columns it has, then use the GetLength property −arr.GetLength(0); arr.GetLength(1);The following is the complete code −Example Live Demousing System; ...

Multi-dimensional arrays are also called rectangular array. You can define a 3-dimensional array of integer as −int [ , , ] a;Let us see how to define a two-dimensional array −Int[, ] a = new[3, 3]The following is an example showing how to work with a multi-dimensional i.e. rectangular array ...

Type casting is converting one type of data to another type. The two forms are −Implicit type conversion − These conversions are performed by C# in a type-safe manner. For example, are conversions from smaller to larger integral types and conversions from derived classes to base classes.Explicit type conversion− These ... Read More

Iterator performs a custom iteration over a collection. It uses the yield return statement and returns each element one at a time. The iterator remembers the current location and in the next iteration the next element is returned.The following is an example −Example Live Demousing System; using System.Collections.Generic; using System.Linq; ...
