C # HASP Login Code

I want to try hasp api to create my custom security behavior, but when I use the code generated by the Sentinel HASP ToolBox, it does not work. I pasted this code from Toolbox into the onLoad form method:

HaspFeature feature = HaspFeature.Default;

string vendorCode = 
"AzIceaqfA1hX5wS+M8cGnYh5ceevUnOZIzJBbXFD6dgf3tBkb9cvUF/Tkd/iKu2fsg9wAysYKw7RMAsV" + 
"vIp4KcXle/v1RaXrLVnNBJ2H2DmrbUMOZbQUFXe698qmJsqNpLXRA367xpZ54i8kC5DTXwDhfxWTOZrB" +

Hasp hasp = new Hasp(feature);
HaspStatus status = hasp.Login(vendorCode);

if (HaspStatus.StatusOk != status)
{
    //handle error
    Application.Exit();
}

Then I inserted the demo version of HASP HL ​​Net key 10 to try it. I always get an error when using this code in the Visual Studio project example, but when I try to use it in the ToolBox, I get the correct answer (HASP_STATUS_OK). Of course, I included a reference to the hasp.net assembly and the added namespace.

What is the reason that it cannot enter the hasp hl key from runtime api in C #?
