ReportExpression-Struktur

Represents a report expression.

Namespace:  Microsoft.ReportingServices.RdlObjectModel
Assembly:  Microsoft.ReportingServices.Designer.Controls (in Microsoft.ReportingServices.Designer.Controls.dll)

Syntax

'Declaration
Public Structure ReportExpression _
    Implements IExpression, IXmlSerializable, IFormattable
'Usage
Dim instance As ReportExpression

public struct ReportExpression : IExpression, 
    IXmlSerializable, IFormattable

public value class ReportExpression : IExpression, 
    IXmlSerializable, IFormattable

[<SealedAttribute>]
type ReportExpression =  
    struct
        interface IExpression
        interface IXmlSerializable
        interface IFormattable
    end

JScript unterstützt die Verwendung von Strukturen, aber nicht die Deklaration neuer Strukturen.

Der ReportExpression-Typ macht folgende Elemente verfügbar.
