vb.net将字符串以指定的字符连接成一个整体字符串的多种方法

在 VB.NET 中，连接字符串的多种方法如下：

1. 使用 String.Join 方法

Dim strArray As String() = {"apple", "banana", "orange"}
Dim delimiter As String = ","
Dim result As String = String.Join(delimiter, strArray)

2. 使用 StringBuilder 类

Dim sb As New StringBuilder()
sb.Append("apple")
sb.Append(",")
sb.Append("banana")
sb.Append(",")
sb.Append("orange")
Dim result As String = sb.ToString()

3. 使用 + 运算符连接字符串

Dim str1 As String = "apple"
Dim str2 As String = "banana"
Dim str3 As String = "orange"
Dim delimiter As String = ","
Dim result As String = str1 + delimiter + str2 + delimiter + str3

4. 使用 & 运算符连接字符串

Dim str1 As String = "apple"
Dim str2 As String = "banana"
Dim str3 As String = "orange"
Dim delimiter As String = ","
Dim result As String = str1 & delimiter & str2 & delimiter & str3

5. 使用 String.Concat 方法

Dim str1 As String = "apple"
Dim str2 As String = "banana"
Dim str3 As String = "orange"
Dim delimiter As String = ","
Dim result As String = String.Concat(str1, delimiter, str2, delimiter, str3)
