What is the method for concatenating strings in Vb?

In VB, you can concatenate strings using the “&” operator or the “+” operator.

For example:

Dim str1 As String = "Hello"
Dim str2 As String = "World"

' 使用&操作符拼接字符串
Dim result1 As String = str1 & " " & str2
Console.WriteLine(result1) ' 输出：Hello World

' 使用+操作符拼接字符串
Dim result2 As String = str1 + " " + str2
Console.WriteLine(result2) ' 输出：Hello World

Additionally, you can concatenate strings using either the String.Concat method or the String.Format method.

For example:

Dim str1 As String = "Hello"
Dim str2 As String = "World"

' 使用String.Concat方法拼接字符串
Dim result1 As String = String.Concat(str1, " ", str2)
Console.WriteLine(result1) ' 输出：Hello World

' 使用String.Format方法拼接字符串
Dim result2 As String = String.Format("{0} {1}", str1, str2)
Console.WriteLine(result2) ' 输出：Hello World
