为什么它会产生错误＆＃34;表达所需＆＃34;？

Public Class WinApp

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    End Sub

    Private Sub buttonSubmit_Click(sender As Object, e As EventArgs) Handles buttonSubmit.Click
        MessageBox.Show("Hello" + ' ' + "how are you");
    End Sub
End Class

Answer 1

要在c＃中运行app，请打开c＃应用程序。 你正在打开vb.net项目并询问c＃代码:) 连接的实际代码在下面的c#

中给出

 private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Hello" + ' ' + "how are you");
        }

Answer 2

MessageBox.Show("Hello" + " " + "how are you")是VB.net代码..您将其与其他代码C＃或C ++代码等混合使用。
