语法

声明
<SerializableAttribute> _
<SqlUserDefinedAggregateAttribute(Format.UserDefined, IsInvariantToDuplicates := True,  _
    IsInvariantToNulls := True, IsInvariantToOrder := True,  _
    IsNullIfEmpty := False, MaxByteSize := )> _
Public Class GeographyCollectionAggregate _
    Implements IBinarySerialize
用法
Dim instance As GeographyCollectionAggregate

[SerializableAttribute]
[SqlUserDefinedAggregateAttribute(Format.UserDefined, IsInvariantToDuplicates = true, 
    IsInvariantToNulls = true, IsInvariantToOrder = true, 
    IsNullIfEmpty = false, MaxByteSize = )]
public class GeographyCollectionAggregate : IBinarySerialize

[SerializableAttribute]
[SqlUserDefinedAggregateAttribute(Format::UserDefined, IsInvariantToDuplicates = true, 
    IsInvariantToNulls = true, IsInvariantToOrder = true, 
    IsNullIfEmpty = false, MaxByteSize = )]
public ref class GeographyCollectionAggregate : IBinarySerialize

[<SerializableAttribute>]
[<SqlUserDefinedAggregateAttribute(Format.UserDefined, IsInvariantToDuplicates = true, 
    IsInvariantToNulls = true, IsInvariantToOrder = true, 
    IsNullIfEmpty = false, MaxByteSize = )>]
type GeographyCollectionAggregate =  
    class 
        interface IBinarySerialize 
    end
