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 As per your question please find below solutions: Array Find int[] array2 = { 1235 }; 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 = {123} y = {45}; int[] z = x.Concat(y); Option2 int[] x = {123} y = {45}; x.AddRange(y); Now you will get updated value in x variable.
