vb.net - 如何从消息框中读取输入？

Question

Microsoft.VisualBasic.Interaction.InputBox("Give an ID to mutate", "Mutation", "Enter your ID");

我能够读取输入，但如何？

另外，如果我按 1 之类的数字，是否有可能获得以下所有信息？

Mp3Player player1 = new Mp3Player(1, "GET Technologies .inc", "HF 410", 4096, 129.95M, 500);

Answer 1

您可以分配结果：

string id = Microsoft.VisualBasic.Interaction.InputBox("Give an ID to mutate", "Mutation", "Enter your ID");

如果您尝试将其转换为数字，则需要将字符串转换为数字：

string idString = Microsoft.VisualBasic.Interaction.InputBox("Give an ID to mutate", "Mutation", "Enter your ID");

int id;
if (int.TryParse(idString, out id))
{
    Mp3Player player = new Mp3Player(id, "GET Technologies .inc", "HF 410", 4096, 129.95M, 500);
}
else
{
     // The user typed something that wasn't a number
}
