得到一个；类型错误“；在vb.net中由C转换而来的代码#

我在VB.Net 2010中有这段代码，我在New（）上遇到了一个“类型错误”

此代码是从C#转换而来的

我做错了什么

Public Function CredentialGet(ByVal sKey As String, ByRef sCred As String)
    Dim sCredential As Element.Credential

    sCredential  = apiclient.SearchCredentials(sSoftwareKey, SessionID,
        New() {New Element.SearchTerm() With {.FilterKey = "APK", .Value = sKey}})
    sCred = sCredential.CredentialID
End Function

新的什么？您缺少一个对象名称。您现在正在传入一个匿名对象。

删除匿名类型的括号。VB.Net在该上下文中不使用它们，而是查找带有关键字的

。函数应该返回一个值。您不返回任何内容，因此请使用Sub：

Public Sub CredentialGet(ByVal Key As String, ByRef Cred As String)
    Dim Credential As Element.Credential 
    Credential = apiclient.SearchCredentials(sSoftwareKey, SessionID, _
        New With {New Element.SearchTerm() With {.FilterKey = "APK", .Value = Key}})
    Cred = Credential.CredentialID
End Sub 

我也质疑这个设计。最好返回一个字符串：

Public Function CredentialGet(ByVal Key As String) As String
    Return apiclient.SearchCredentials(sSoftwareKey, SessionID, _
        New With {New Element.SearchTerm() With {.FilterKey = "APK", .Value = Key}}).CredentialID
End Function
