"foreach" loop in C#

Raga Deepthi G.
30/03/2018 0 1

foreach is a looping statement :

  • repeats a group of statements for each element in an array or an object collection. (or)
  • used to iterate through the collection/ an array to get the required information.

Advantages:

  • Easy implementation.
  • Least possibility of errors. [ especially when working with index based values, like in arrays. ]

Syntax:

foreach(<datatype of collection / array> <variablename> <in> <collection/array>)
{

code....

}

Example:

foreach(string courseName in coursesList)
{

code....

}

  • here, coursesList is a string collection
  • string courseName is called as the "loop variable" which represents the element from the collection in each iteration.
  • in is the pre-defined keyword

Working style of foreach loop:

  • data type of loop variable must and should be the same as the data type of the array/collection that has to be referred.
  • At the time of execution, first the foreach loop goes to the array/collection, counts the number of elements & repeats the loop that many times automatically.
  • At each iteration array/collection location value will be copied into loop variable.

Example 1: In the below example, we'll see how to iterate a group of int type array elements using foreach loop.

 

 

Example 2: In the below example, we'll see how to iterate a group of values in a collection.

NOTE : in .NET we've different types of collections. For example we took "List" a generic collection
