How to traverse through this IEnumerator

I got an IEnumerator type from a ConcurrentDictionary . I am trying to iterate through it using the following way

    System.Collections.Generic.IEnumerator<System.Collections.Generic.KeyValuePair<string,string>>

    Ien  = Concur_Dictionary.GetEnumerator();

    foreach (KeyValuePair<string, string> pair in Ien) -->Error here
    {
    }

I get the following error 

Error   4   foreach statement cannot operate on variables of type 'System.Collections.Generic.IEnumerator<System.Collections.Generic.KeyValuePair<string,string>>' because 'System.Collections.Generic.IEnumerator<System.Collections.Generic.KeyValuePair<string,string>>' does not contain a public definition for 'GetEnumerator'

Any suggestions on how I could iterate through this IEnumerator ?

You can use MoveNext() of it.

var enumerator = getInt().GetEnumerator();
while(enumerator.MoveNext())
{
    //Line of codes..
}

You can do something like this.

Or this can be done.

foreach (var item in collection)
{
    // do your stuff   
}

Try this thing it worked for me.

You usually don't want to iterate through the IEnumerator; you just iterate over the IEnumerable directly:

foreach (var pair in Concur_Dictionary) …

If, for some reason, you don't have access to the IEnumerable, you can do this:

while (Ien.MoveNext())
{
    var pair = Ien.Current;
    …
}
