wpf登录窗体跳转怎么做

你把启动页设置成MainWindow主界面，然后在加载MainWindow时新增事件跳转到登陆界面，登陆完成关闭登陆界面就好了。

MainWindow.cs:

this.SourceInitialized += Index_SourceInitialized

private void Index_SourceInitialized(object sender, EventArgs e)

{

Login login = new Login()

login.ShowDialog()

}

Login.cs:

if(登陆成功) this.Close()

Event Form1.Load

Form1.Timer1.Enabled = True //默认定时器是启动状态，所以要先停止

Form1.Timer1.Interval = 1//设置定时器循环的间隔时间（单位：毫秒）

End Event

Event Form1.Timer1.Timer

Key=GetLastKey()

// 112 = F1

If Key = 112 Then

Form1.ComboBox1.ListIndex = 0

ElseIf Key = 113 Then

Form1.ComboBox1.ListIndex = 1

ElseIf Key = 114 Then

Form1.ComboBox1.ListIndex = 2

ElseIf Key = 115 Then

Form1.ComboBox1.ListIndex = 3

ElseIf Key = 116 Then

Form1.ComboBox1.ListIndex = 4

ElseIf Key = 117 Then

Form1.ComboBox1.ListIndex = 5

ElseIf Key = 118 Then

Form1.ComboBox1.ListIndex = 6

End If

End Event
