Question

我希望能够通过用户输入的内容引用变量：例如：

Dim str1 As String = "sherrifs"
Dim str2 As String = "cowboys"
Dim str3 As String = "aliens"
Dim strUserInput As String
    Console.WriteLine("Please enter a variable name: ")
    strUserInput = Console.ReadLine()

如果用户输入str1，那么输出应该是sherrifs等。我将如何在vb.net中执行此操作？感谢

最好的方法是将您的商品保存在Dictionary<string, string>对象中。将key保存为variableName，value为variableValue。

Dictionary<string, string> variableList = new Dictionary<string, string>()
variableList.Add("str1", "sherrifs")
variableList.Add("str2", "cowboys")
variableList.Add("str3", "aliens")

Dim strUserInput As String
Console.WriteLine("Please enter a variable name: ")
strUserInput = Console.ReadLine()

If variableList.ContainsKey(strUserInput) Then
   Console.WriteLine(variableList(strUserInput))
Else
   Console.WriteLine ("No luck")

使用用户输入的文本来引用/调用变量VB.NET中的数据
