示例1: Example
Module Example
Public Sub Main()
Dim value1 As String = "This is a string."
Dim value2 As String = value1
Console.WriteLine(value1)
Console.WriteLine(value2)
End Sub
End Module輸出：
This is a string. This is a string.
示例2: charArr1
' Unicode Mathematical operators
Dim charArr1() As Char = {ChrW(&H2200), ChrW(&H2202), _
ChrW(&H200F), ChrW(&H2205)}
Dim szMathSymbols As New String(charArr1)
' Unicode Letterlike Symbols
Dim charArr2() As Char = {ChrW(&H2111), ChrW(&H2118), _
ChrW(&H2122), ChrW(&H2126)}
Dim szLetterLike As New String(charArr2)
' Compare Strings - the result is false
Console.WriteLine("The strings are equal? " & _
CStr(szMathSymbols.Equals(szLetterLike)))示例3: String
' Create a Unicode String with 5 Greek Alpha characters
Dim szGreekAlpha As New String(ChrW(&H0391), 5)
' Create a Unicode String with a Greek Omega character
Dim szGreekOmega As New String(New Char() {ChrW(&H03A9), ChrW(&H03A9), _
ChrW(&H03A9)}, 2, 1)
Dim szGreekLetters As String = String.Concat(szGreekOmega, szGreekAlpha, _
szGreekOmega.Clone())
' Examine the result
Console.WriteLine(szGreekLetters)
' The first index of Alpha
Dim iAlpha As Integer = szGreekLetters.IndexOf(ChrW(&H0391))
' The last index of Omega
Dim iomega As Integer = szGreekLetters.LastIndexOf(ChrW(&H03A9))
Console.WriteLine("The Greek letter Alpha first appears at index {0}.", _
ialpha)
Console.WriteLIne("The Greek letter Omega last appears at index {0}.", _
iomega)
