How to use if statement for validate.exists function in C# [closed]

I am new to programming. Please help me with this. I want to use validate.exists function as my condition in the code like below. if it returns true I want to exit the module and if it returns false other modules should be executed.

public void ITestModule()  
    {

        Report.Log(ReportLevel.Info, "Validation", "Validating Exists on item 'Internet.abc.Connexion.Deconnexion'.", repo.Internet.abc.Connexion.DeconnexionInfo, new RecordItemIndex(0));
        if (Validate.Exists(repo.Internet.abc.Connexion.DeconnexionInfo))
        {
            Report.Success("Connected");
            return;     
        }
        else
        {
            Delay.Milliseconds(0);
            Report.Log(ReportLevel.Info, "Mouse", "Mouse Left Click item 'Internet.abc.Connexion.Httpsxyz' at Center.", repo.Internet.abc.Connexion.Httpsxyz, new RecordItemIndex(1));
            repo.Internet.abc.Connexion.Httpsxyz.Click();
            Delay.Milliseconds(200);
        }

    }
