语法

声明
Public Structure ReportExpression(Of T As {Structure, New}) _
    Implements IExpression, IXmlSerializable, IFormattable
用法
Dim instance As ReportExpression(Of T)

public struct ReportExpression<T> : IExpression, 
    IXmlSerializable, IFormattable
where T : struct, new()

generic<typename T>
where T : value class, gcnew()
public value class ReportExpression : IExpression, 
    IXmlSerializable, IFormattable

[<SealedAttribute>]
type ReportExpression<'T when 'T : struct, new()> =  
    struct
        interface IExpression
        interface IXmlSerializable
        interface IFormattable
    end

JScript 不支持一般类型和方法。
