示例

下面的示例演示如何声明和使用 FixedLengthStringThe following example demonstrates how to declare and use a FixedLengthString.

Private Sub DemoFixedLengthString()  
    ' Declare a string that has a length of 7 characters and assign the  
    ' initial string. The additional 5 positions will be padded with  
    ' spaces.  
    Dim fixedString As New FixedLengthString(7, "He")  
    ' Display the string in a message box.  
    MsgBox(fixedString.ToString)  
    ' Assign a new value to the string.  
    fixedString.Value = "Hello World"  
    ' Display again. Note that only the first 7 characters are shown.  
    MsgBox(fixedString.ToString)  
End Sub  

注解

FixedLengthString类可用于模拟 Visual Basic 6.0 字符串的行为,这使你可以声明具有固定长度的字符串。The FixedLengthString class can be used to emulate the behavior of a Visual Basic 6.0 string, which enables you to declare a string with a fixed length. FixedLengthString不能转换为 String ; 必须引用 Value 属性或调用 ToString 方法来转换类型。A FixedLengthString cannot be converted to a String; you must either reference the Value property or call the ToString method to convert the type.

备注

Microsoft.VisualBasic.Compatibility.VB6 命名空间中的函数和对象用于工具从 Visual Basic 6.0 升级到 Visual Basic 2008。Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic 2008. 多数情况下,这些函数和对象可再现 .NET Framework 中其他命名空间的功能。In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework. 只有当 Visual Basic 6.0 代码模型与 .NET Framework 实现有显著区别时,才必须使用这些函数和对象。They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.
