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.
The ReportExpression type exposes the following members.
