语法错误，'(' - C#

Question

I'm working with C# (in asp.net) and i'm trying to add nested IF in a correct way but i keep getting this 3 errors with the second if (chk1==checked) that say Syntax error, '(' expected , ) expected and ) expected ! can someone help me ?

my code :

protected void CreateUser_Click(object sender, EventArgs e)
{
    var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
    var signInManager = Context.GetOwinContext().Get<ApplicationSignInManager>();
    var user = new ApplicationUser() { UserName = Email.Text, Email = Email.Text };
    IdentityResult result = manager.Create(user, Password.Text);
    if (result.Succeeded)
    {
        if (chk1==checked)
        {
            signInManager.SignIn( user, isPersistent: false, rememberBrowser: false);
            IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response);
        } else 
            Response.Write("Sorry");

    }
    else 
    {
        ErrorMessage.Text = result.Errors.FirstOrDefault();
    }
}

Answer 1

"checked" is a reserved keyword in C#. I think you are confusing the compiler by using it. Try renaming that.

Answer 2

Checked is the boolean property of chk1 , therefore the correct way for your needs will be:

protected void CreateUser_Click(object sender, EventArgs e)
{
    var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
    var signInManager = Context.GetOwinContext().Get<ApplicationSignInManager>();
    var user = new ApplicationUser() { UserName = Email.Text, Email = Email.Text };
    IdentityResult result = manager.Create(user, Password.Text);
    if (result.Succeeded)
    {
        if (chk1.Checked)
        {
            signInManager.SignIn( user, isPersistent: false, rememberBrowser: false);
            IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response);
        } else 
            Response.Write("Sorry");

    }
    else 
    {
        ErrorMessage.Text = result.Errors.FirstOrDefault();
    }
}

Answer 3

checked is a keyword in C#. I think what you want is to check if the chk1 checkbox has a checked value, which you would do like this:

if(chk1.Checked == true)
{

}

or more simply:

if(chk1.Checked)
{

}
