How to increase the programming rate by VB.NET enumeration
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.
After reading this article, I believe you have a certain understanding of "how to increase the programming speed of VB.NET enumeration". If you want to know more about it, you are welcome to follow the industry information channel. Thank you for reading!
