Hi

  It is giving error Object reference not set to an instance of the object.

string html = "";
            html += "";
            html += "";
            html += "";
            this.webBrowser1.DocumentText = string.Format(html, "https://www.youtube.com/watch?v=5dFvl3mS8-U".Split('=')[1]);

Thanks

Hi,

if ("htp://youtu.be/faT7y8NiZ20".Split('=').length>0){

this.webBrowser1.DocumentText = string.Format(html, "htp://youtu.be/faT7y8NiZ20".Split('=')[1]);

}

As, Sam sir said , clearly there is no '=' in your url so the split function is throwing the error. please modify your url.

generally the youtuble url is like this

www.youtube.com/watch?v=sS5BCvj6c_0

this url will work when you will split.

When you get an error like that you can split the code as in the following.

string html = "Result: {0}";
string url = "htp://youtu.be/faT7y8NiZ20";
string[] sa = url.Split('=');
string s = sa[0];
Console.WriteLine(string.Format(html, s));
s = sa[1];
Console.WriteLine(string.Format(html, s));

When you run that you will see that a[0] has the entire contents of html but a[1] does not exist and therefore it causes the error. There is no '=' in the input string.

Programmers prefer to do many things in one line of code but that can cause a problem when there is an error, it is more difficult to find the cause of the error.
