ReportExpression Structure

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 suports the use of structures, but not the declaration of new ones.
