Vb.net Vb+带参数的自定义Url

如何使用参数自定义url？ 在我的示例中，我有3个参数

Textbox1.Text = "Ikea"
Textbox2.Text = "Table"
Textbox3.Text = "Black"

最终的url需要如下所示：

https://localhost/objects?color=Black&manufacturer=Ikea&type=Table

在Textbox4.Text中

那么我如何添加previous文本框的previous值呢？ 目前我有：

Private Sub FinalScrapper_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    TextBox1.Text = "Ikea"
    TextBox2.Text = "Table"
    TextBox3.Text = "Black"

    TextBox4.Text = ("https://localhost/objects?color=Black&manufacturer=Ikea&type=Table")
    'The correct parameters are something like that ?
    'TextBox4.Text = ("https://localhost/objects?color=TextBox3.Text&manufacturer=TextBox1.Text&type=TextBox2.Text")
End Sub

谢谢。

我使用了注释中建议的插值字符串，以下内容对我很有用：

Private Sub FinalScrapper_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    TextBox1.Text = "Ikea"
    TextBox2.Text = "Table"
    TextBox3.Text = "Black"

    Dim manufacturer = TextBox1.Text
    Dim type = TextBox2.Text
    Dim color = TextBox3.Text

    Dim s1 = $"https://localhost/objects?color={color}&manufacturer={manufacturer}&type={type}"
    TextBox4.Text = s1
End Sub

看看：或者VB中连接字符串的最基本方法是string1&string2或stringVar1&stringVar2，您也可以使用+而不是&作为字符串连接运算符。你需要知道，虽然这不是这个特殊情况下的最佳选择。杰夫的建议更为恰当。对于这种情况，或者如果您使用的是旧版本的VB，我会使用插值字符串。谢谢您提供的提示。可能会重复
