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


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.


Solution

  • Character vs key

    % => alt , + => shift and ^ is used for ctrl key

    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 to achieve ctrl shift F1 you will send following

    ^+{F1}
