Question

在VB.NET中，我正在查看一行代码，该代码将以下值传递给将参数定义为“object”类型的过程。

New Object() {gClient.ContactManager, LyncUri}

这是完整的相关代码

Dim gClient As Microsoft.Lync.Model.LyncClient
gClient = Microsoft.Lync.Model.LyncClient.GetClient()

    gClient.ContactManager.BeginSearch(LyncUri,
        Ly.SearchProviders.GlobalAddressList,
        Ly.SearchFields.EmailAddresses,
        Ly.SearchOptions.IncludeContactsWithoutSipOrTelUri,
        1,
        AddressOf SearchCallback,
        New Object() {gClient.ContactManager, LyncUri})

和程序定义

Public Function BeginSearch(searchString As String, providers As Microsoft.Lync.Model.SearchProviders, searchFields As Microsoft.Lync.Model.SearchFields, searchOptions As Microsoft.Lync.Model.SearchOptions, maxResults As UInteger, contactsAndGroupsCallback As System.AsyncCallback, state As Object) As System.IAsyncResult

我见过对象初始化代码，它通过使用{property1 = value1，property2 = value}的语法格式在括号内指定属性值来初始化对象的属性，例如，上面的代码到底是做什么的？

New Object()创建一个数组对象。 {braces}之间的内容是初始化数组的元素。详细的语法糖非常方便：

dim arr = New Object(1)
arr(0) = gClient.ContactManager
arr(1) = LyncUri
