Upendra Pratap Shahi · Answer

Hello Use below code- For check array element- public void checkArray() { string stringToCheck = "GHI" ; string [] stringArray = { "ABC" , "DEF" , "GHI" , "JKL" }; foreach ( string x in stringArray) { if (x.Equals(stringToCheck)) { Response.Write( "Find the string ..." + x); } else { //write your code here } } } For Combined array- public void mergeArray() { // ::: Declare two integer arrays with five elements each int [] array1 = { 1, 2, 3, 4, 5 }; int [] array2 = { 6, 7, 8, 9, 10 }; // ::: Loop through the two arrays and print them Response.Write( "First Array " ); foreach ( int element in array1) { Response.Write(element + " " ); } Response.Write( "Second Array " ); foreach ( int element in array2) { Response.Write(element + " " ); } // ::: Create new List of integers and call AddRange twice var list = new List int >(); list.AddRange(array1); list.AddRange(array2); // ::: Call ToArray to convert List to array int [] array3 = list.ToArray(); // ::: Loop through array elements of combined array and print them Response.Write( "CombindArray " ); foreach ( int element in array3) { Response.Write(element+ " " ); } }

Hi, Write like this.. string stringToCheck = "GHI"; string[] stringArray = { "ABC", "DEF", "GHI", "JKL" }; foreach (string x in stringArray) { if (x.Equals (stringToCheck)) { MessageBox.Show("Find the string ..." + x); } } Ref : http://csharp.net-informations.com/collection/csharp-array.htm

Hi, As per your question please find below solutions: Array Find int[] array2 = { 1,2,3,5 }; Option1 // Check if you are getting 5 then exists otherwsie you will get 0 int value2 = Array.Find(array2, element => element == 5); Option2 // Check index if it is greater than 0 then it exist otherwise not int index1 = Array.IndexOf(array2, 10); Option3 // Check if it is going inside if block then it exists if (array2.Contains(8)) { } Array Combine Option1 int[] x = {1,2,3}, y = {4,5}; int[] z = x.Concat(y); Option2 int[] x = {1,2,3}, y = {4,5}; x.AddRange(y); Now you will get updated value in x variable.
