Explanation: * Regex.Matches

Searches an input string for all occurrences of a regular expression and returns all the matches.

  • MatchCollection

    Represents the set of successful matches found by iteratively applying a regular expression pattern to the input string.

  1. var2 = ((Listlt;intgt;) array1) [0];

  2. var2 = array1[0].Equals(typeof(int));

  3. var2 = Convert.ToInt32(array1[0]);

  4. var2 = ((int[])array1)[0];

Answer: A

Explanation: Make a list of integers of the array with = ( (Listlt;intgt;)arrayl) then select the first item in the list with [0].

    Explanation: * WebRequest.Create Method (Uri)

    Initializes a new WebRequest instance for the specified URI scheme.

    • Example:

      1. To request data from a host server

        Create a WebRequest instance by calling Create with the URI of the resource. C#

        WebRequest request = WebRequest.Create(quot;http://www.contoso.com/quot;);

      2. Set any property values that you need in the WebRequest. For example, to enable authentication, set the Credentials property to an instance of the NetworkCredential class. C#

        request.Credentials = CredentialCache.DefaultCredentials;

      3. To send the request to the server, call GetResponse. The actual type of the returned

        WebResponse object is determined by the scheme of the requested URI. C#

        WebResponse response = request.GetResponse();

      4. To get the stream containing response data sent by the server, use the GetResponseStream method of the WebResponse.

        C#

        Stream dataStream = response.GetResponseStream ();
