How simulate CTRL+V keystrokes (paste) using C#

问题

How can we simulate CTRL+V keys (paste) using C#?

I have a textbox that hasn't a id for access, for example textbox1.Text = someValue won't work here.
I want to fill that textbox (from clipboard) by clicking on it. For some reasons we exactly need simulate CTRL+V, mean we cannot use external libraries like inputsimulator.

回答1:

Code for modifying keys

alt = % , shift = + and ctrl = ^

Original Answer:

Simulation of single modifier key with another key is explained below Step1: Focus the textBox, on which you want to perform two keys and then Step2: send the key for example control-v will be sent like "^{v}". Here is the code

        target_textBox.Focus();
        SendKeys.Send("^{v}");

target_textBox.Focus(); is needed only when target textbox is not focused at the time of sending key

Update:

For sending three keys (two modifying keys plus other key) like ctrl shift F1 you will do

^+{F1}

回答2:

Why don't you override the TextBox OnClick event than when the event is called, set the Text property to Clipboard.GetText()

Like:

private void textBox1_Click ( object sender, EventArgs e )
{
        textBox1.Text = Clipboard.GetText ();
}

回答3:

This function is already built in: TextBoxBase.Paste()

textbox1.Paste();

回答4:

some JS do not permit to change value in usual way

inputList[21].SetAttribute("value", txtEMail.Text);

you should try something like this:

inputElement.InvokeMember("focus");
inputElement.InvokeMember("click"); //sometimes helpfull
Clipboard.SetDataObject(txtEMail.Text);
SendKeys.Send("^(v)");

//but not "^{v}"
