如何通过单击从 Proses Vb Net 获取响应时间

Question

我想获得一个简单数学值的响应时间 如果按下“按钮计算”，则在文本框中获取总和值 a 和值 b，并在文本框中显示进行该数学计算（响应时间）的时间。

编码按钮计算

Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
    Timer1.Start()
    Me.stopwatch.Start()
    TextBox3.Text = Val(TextBox1.Text) + Val(TextBox2.Text)
    ListBox1.Items.Add(ListBox1.Items.Count + 1 & " " & Label1.Text)

End Sub

"textbox4.text (显示计算的时间以毫秒为单位)"

Answer 1

Dim sw = New System.Diagnostics.Stopwatch()
sw.Start()

Timer1.Start()
Me.stopwatch.Start()
TextBox3.Text = Val(TextBox1.Text) + Val(TextBox2.Text)
ListBox1.Items.Add(ListBox1.Items.Count + 1 & " " & Label1.Text)

sw.[Stop]()
' time is a timespan that represents the time passed between sw.Start() and sw.Stop().
textbox4.Text = sw.ElapsedMilliseconds.ToString()
