Sending multiple lines of text

[Davider]

the following code, in many controls, can only send partial text, sometimes only the first line of text, sometimes only the first two lines of text
It seems that the Enter key is being interpreted in multiline text
 

Code:

Copy      Help

string R="""
hello：

world？

Hi！
""";
e.MouseClick();

keys.send("Ctrl+A", $"!{R}"); //NO

keys.sendt(R);  //NO

clipboard.paste(R); //OK
