How to find length of array without using builtin functions in C#?

Question

Sachin Singh · Answer

If you don't want to use Array.Length then int count=0; foreach(var item in YourArray) { count=count+1; } Console.WriteLine( "Array length is {0}" ,count); And, yes the above code doesn't make any sense, nobody will ever ask you to find length without using the length property, So, just use the Length property. If you are practicing array concepts then better practice sorting and searching, that may help in interviews or in general.

Hello Daanish If you want to find array length without using any in-build function then you can use foreach loop and get total count of loop. int lengthCount=0; foreach(var item in ArrayList) { lengthCount=lengthCount+1; } Console.WriteLine("Total array length = {0}",lengthCount);

You can use a list to get the number of item in your array.here is an example: Listproject = new List(); foreach(var item in YourArray) { project.Add(item); } Console.WriteLine("Array length is {0}",project.Count);
