Jul 21, 2013 · You'll need to loop through the array using the Array.GetLowerBound and Array.GetUpperBound methods. The Array.IndexOf and Array.FindIndex methods don't support multidimensional arrays. For example:

Jul 16, 2010 · Here is a method that should find an index in an array with an arbitrary rank. ... Added Upper/Lower bounds range per rank. public static int[] FindIndex(this Array haystack, object needle) if (haystack.Rank == 1) return new[] { Array.IndexOf(haystack, needle) }; var found = haystack.OfType<object>() .Select((v, i) => new { v, i })

To access an element of a two-dimensional array, you must specify two indexes: one for the array, and one for the element inside that array. Or better yet, with the table visualization in mind; one for the row and one for the column (see example below).

Aug 20, 2018 · I want to know how would I use IndexOf method if I wanted to call specific index and display the array elements inside of it? For example, my three textboxes set the following data to 3 elements of each index: CarName = "Audi" Model = "A3" color = "black" cars.Add(new string[3]); cars[cars.Count-1][0] = textBox1.Text;

Mar 23, 2019 · Element in the 2D array is stored in the matrix form. The first index shows the row of the matrix and the second index shows the column of the matrix. Example: int [,] matrix = new int [3,3]; 2D Array in Memory Representation is shown below. To access elements in the zeroth index we need to specify two indexes matrix [0] [0].

Feb 6, 2025 · In C#, indexers are special members that allow objects to be indexed similarly to arrays. Multi-dimensional indexers in C# are the same as multidimensional arrays. We can efficiently retrieve data with a multi-dimensional indexer by …

Nov 14, 2023 · Ranges and indices provide a succinct syntax for accessing single elements or ranges in a sequence. In this tutorial, you'll learn how to: Use the syntax for ranges in a sequence. Implicitly define a Range. Understand the design decisions for the start and end of each sequence. Learn scenarios for the Index and Range types.

In the above example, the value of a two-dimensional array can be accessed by index no of row and column as [row index, column index]. So, [0, 0] returns the value of the first row and first column and [1, 1] returns the value from the second row and second column.

Nov 29, 2023 · 2D array. A two-dimensional array is used to store elements that are indexed by two coordinates. In C# we separate the indexes with a comma. We can create 2D arrays of any element type.

Dec 5, 2021 · This post will discuss how to find the index of an element in an array in C#. The solution should either return the index of the first occurrence of the required element or -1 if it is not present in the array. 1. Using Array.IndexOf() method.
