How to loop through a collection that supports IEnumerable

Question

User · Answer

or even a very classic old fashion method

IEnumerable<string> collection = new List<string>() { "a", "b", "c" };

for(int i = 0; i < collection.Count(); i++) 
{
    string str1 = collection.ElementAt(i);
    // do your stuff   
}

maybe you would like this method also :-)

Maybe you forgot the await before returning your collection

Along with the already suggested methods of using a foreach loop  I thought I d also mention that any object that implements IEnumerable also provides an IEnumerator interface via the GetEnumerator method  Although this method is usually not necessary  this can be used for manually iterating over collections  and is particularly useful when writing your own extension methods for collections   IEnumerable lt T gt  mySequence  using  var sequenceEnum   mySequence GetEnumerator          while  sequenceEnum MoveNext                     Do something with sequenceEnum Current            A prime example is when you want to iterate over two sequences concurrently  which is not possible with a foreach loop
