Today, I will talk to you about how to understand the two applications of the VB.NET serial operator, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

Today, let's take a look at the relevant application skills of the VB.NET concatenation operator to improve our understanding of the language.

The VB.NET concatenation operator joins multiple strings into a single string. There are two concatenation operators: + and &. Both VB.NET concatenation operators perform basic concatenation operations, as shown in the following example.

Visual Basic

Dim x As String = "Con"

& "caten" & "ation"

Dim y As String = "Con" +

"caten" + "ation"

'The preceding statements

Set both x and y to

"Concatenation".

These two operators can also concatenate String variables, as shown in the following example.

Visual Basic

Dim an As String = "abc"

Dim d As String = "def"

Dim z As String = a & d

Dim w As String = a + d

'The preceding statements

Set both z and w to "abcdef".

The difference between two VB.NET concatenation operators

If you perform a large number of operations on strings, such as concatenation, deletion, or substitution, performance may be improved through the StringBuilder class in the System.Text namespace. This class takes extra instructions to create and initialize the StringBuilder object and uses other instructions to convert its final value to String, but at this point you may revert to using StringBuilder because it executes faster.

After reading the above, do you have any further understanding of how to understand the two applications of the VB.NET concatenation operator? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
