C# - Access variable Names dynamically

Question

I am automating a web page. i have captured and saved the Links in a file.

Link Url_0="gmail.com"
Link Url_1="ymail.com"
Link Url_2="hotmail.com"
Link Url_3="outlook.com"

The below statement will click on each url.

HomePage.Url_0.Click();//Homepage is the Class name

I want to Click these URLs one by one. So I am using a for loop.

for(int i=0;i<3;i++)
{
String url=String.Format("Url_{0}",i);
HomePage.url.Click(); //This is throwing me error (I think that this is not correct way to do.)
Sleep(2000);
}

How can I proceed here ? Can this be done in any way ? Any help is appreciated.

Answer 1

You should put the variables into a collection, rather than having a different variable with a different name for each. It's technically possible to access the variable in the manor you describe, but it's not what a language like C# is designed to do, and would be very bad practice.

There are several collections to choose from. Here a List is probably appropriate, an array could work as well.

List<string> urls = new List<string>()
{
    "gmail.com",
    "ymail.com",
    "hotmail.com",
    "outlook.com"
};

foreach (string url in urls)
{
    //do whatever with the url
    Console.WriteLine(url);
}

You can store all links you want into a Coolection of type: IList<Link> or into an IEnumerable<Link>

IList<Link> myCollection = new List<Link>();

After that, you'll go throuh items in the collection with an

foreach(var item in myCollection ) {
      //Here implement your logic with click
}
