Editor to share with you how to increase the programming speed of VB.NET enumeration, I hope you will gain something after reading this article, let's discuss it together!

Take VB.NET as an example to explain the methods to improve the related efficiency. It is mainly for the use of VB.NET enumerations to achieve efficiency improvement.

When you still use For... When the Each loop or the For 1 To Count loop processes collections, a new technology, the IEnumerator interface, is added to VB .NET.

The IEnumerator interface supports two methods and one feature. The MoveNext method can move one record at a time in the collection. The Reset method resets the enumerator to the beginning of the collection. The Current feature returns the current record from the collection.

The following VB.NET enumerator shows these three possible ways to calculate collections.

Dim testCollection As New Collection ()

Dim collectionItem As String

Dim loopCounter As Integer

Dim enumCollection As Ienumerator

With testCollection

.add ("1")

.add ("2")

.add ("3")

End With

For Each collectionItem In

TestCollection

Console.Out.WriteLine (collectionItem)

Next

For loopCounter = 1 To

TestCollection.Count

Console.Out.WriteLine

(testCollection.Item (loopCounter))

Next

EnumCollection = testCollection.

GetEnumerator ()

Do While enumCollection.MoveNext

Console.Out.WriteLine

(enumCollection.Current)

Loop

IEnumerator brought you For... The counting function that Each technology can provide, in addition, VB.NET enumeration has a new function to reset the loop and start from the starting position.
