[英]C# Using With Equivalent in VB.NET
var baseAddress = new Uri("http://www.aaa.com");
var cookieContainer = new CookieContainer();
using (var handler = new HttpClientHandler() { CookieContainer = cookieContainer })
using (var client = new HttpClient(handler){ BaseAddress = baseAddress })
{}
I tried to convert this code with the Developer Fusion tool to VB.NET but was not successful. 我尝试使用Developer Fusion工具将此代码转换为VB.NET,但未成功。
Dim baseAddress = New Uri("http://www.aaa.com")
Dim cookieContainer = New CookieContainer()
Using handler = New HttpClientHandler() With { _
Key .CookieContainer = cookieContainer _
}
Using client = New HttpClient(handler) With { _
Key .BaseAddress = baseAddress _
}
End Using
End Using
an error occured "key . " 错误发生了“键”。
What is the VB.NET equivalent of this code (using with
statement)? VB.NET的等效代码是什么( with
语句一起使用)?
Just remove the Key
word 只需删除Key
Using handler = New HttpClientHandler() With { _
.CookieContainer = cookieContainer _
}
Using client = New HttpClient(handler) With { _
.BaseAddress = baseAddress _
}
End Using
End Using
I learnt something new ( Object Initializers: Named and Anonymous Types ) from Kilanny's answer; 我从Kilanny的答案中学到了新的东西( 对象初始化器:命名和匿名类型 )。 here's how I refactored the converted code: 这是我重构转换后的代码的方式:
Dim baseAddress = New Uri("http://www.aaa.com")
Dim cookieContainer = New Net.CookieContainer()
Using handler As New HttpClientHandler
With handler
.CookieContainer = cookieContainer
Using client As New HttpClient(handler)
With client
.BaseAddress = baseAddress
End With
End Using
End With
End Using
