This article shares with you the content of a sample analysis of VB.NET file objects. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

VB.NET is a language based on. Net framework SDK released by Microsoft. It has the same application mechanism as Java, can achieve code hosting, and has powerful object-oriented features. Below, we can make a detailed interpretation of the language through the introduction of VB.NET file objects.

The VB.NET file object represents a file, and there are some very useful ways to verify the existence of a file and to rename and delete a file. For example:

Dim fl as File fl=new File ("foo.txt") if (fl.Exists)'if the file exists fl.Delete 'delete it End If

Users can also use the File object to get a FileStream object, and then read and write file data by using the FileStream object:

Dim ts as TextStream Dim fs as FileStream ts=fl.OpenText 'open a text file for reading fs=fl.OpenRead' open any file for reading

(1) VB.NET file object reads a text file (TextFile)

To read a text file, the user can use the File object to get a StreamReader object, and then use the text stream (text stream) reading method:

Dim ts as StreamReader ts=fl.OpenText () s=ts.readLine

(2) VB.NET file object to write a text file (Write a Text File)

To create and write a text file, the user can get a StreamWrite object using the CreateText method, and then perform operations, such as:

Dim sw as streamWriter sw=fl.CreateText sw.writeLine ("write text into file")

If you want to operate on an existing file, you can use an object with logical parameters to do so:

Sw=new StreamWriter (path,true) Thank you for your reading! This is the end of this article on "sample Analysis of VB.NET File objects".
