程序集：  Microsoft.Data.Edm（在 Microsoft.Data.Edm.dll 中）

语法

声明
Public Delegate Function TryCreateObjectInstance ( _
    edmValue As IEdmStructuredValue, _
    clrType As Type, _
    converter As EdmToClrConverter, _
    <OutAttribute> ByRef objectInstance As Object, _
    <OutAttribute> ByRef objectInstanceInitialized As Boolean _
) As Boolean
用法
Dim instance As New TryCreateObjectInstance(AddressOf HandlerMethod)

public delegate bool TryCreateObjectInstance(
    IEdmStructuredValue edmValue,
    Type clrType,
    EdmToClrConverter converter,
    out Object objectInstance,
    out bool objectInstanceInitialized
)

public delegate bool TryCreateObjectInstance(
    IEdmStructuredValue^ edmValue, 
    Type^ clrType, 
    EdmToClrConverter^ converter, 
    [OutAttribute] Object^% objectInstance, 
    [OutAttribute] bool% objectInstanceInitialized
)

type TryCreateObjectInstance = 
    delegate of 
        edmValue:IEdmStructuredValue * 
        clrType:Type * 
        converter:EdmToClrConverter * 
        objectInstance:Object byref * 
        objectInstanceInitialized:bool byref -> bool
