ReportExpression 结构
Represents a report expression.
命名空间: Microsoft.ReportingServices.RdlObjectModel
程序集: Microsoft.ReportingServices.Designer.Controls(在 Microsoft.ReportingServices.Designer.Controls.dll 中)
语法
声明
Public Structure ReportExpression _
Implements IExpression, IXmlSerializable, IFormattable
用法
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 支持使用结构,但不支持声明新结构。
