SendKeys

A tiny executable to send key input to any process by passing command line arguments to it. Use it to save yourself from adding refereces to System.Windows.Forms, for example in .NET Core or .NET Standard projects.

SendKeys has no dependencies besides the .NET Framework 2.0 and can be deployed with any installer, for example.

Examples

Send keys to process 4711 and commit by sending an Enter key:

SendKeys.exe -pid:4711 "format C:{Enter}"

Same but wait 3 seconds upfront:

SendKeys.exe -pid:4711 "format C:{Enter}" -wait:3000

Noteworthy

As always, you'll need to add quotes to the argument string if it contains spaces (like shown in the examples). Otherwise, Windows will split it up as multiple arguments.
