Information Processing Techniques Lab1 and Lab2

LAB 1

Question 1:Write a C# program (Console Application) which will accept string input from user and create a new stringwith first 4 characters will be in lower caseand rest of the letter will be upper case.

Question 2:Write a C# program (Console Application) which will take matrix size as input from user then generate a random matrix and find sum of left diagonals of a matrix.

Question 3:Create a class ‘Calculator’ which would have the following methods: • Add • Subtract • Multiple • Divide Now overload theAddmethod to accommodate multiple parameters (i.e. 2 parameters, 3 parameters, and n number of parameters).

Question 4:Create a class ‘Student’ with the following properties: • Name • Year of Birth • Semester • GPA Implement the IComparable<> interface so that you can use the Sort method. You should be able to sort the List in descending order of GPA.

Question 5:You have two character arrays (strings). You have to compare if both the values are equivalent or not using the below method?
string string1 = new string(new char[] { 'h', 'e', 'l', 'l', 'o' }); string string2 = new string(new char[] { 'h', 'e', 'l', 'l', 'o' }); public static bool CompareObjects (object name, object name2) { }

LAB 2

Question No 1:Generate an array of 1 million random numbers and perform ‘searching’ on that arrayto find all occurrences of the given number.Measure time difference on the following techniques: •Search the Array on one thread (no threading code required) •Search Array using 5 different threads You should print the time taken when no thread was used and when 5 different threads are used. Display the indices on which the data was found. Note: You can use the following code to start a parameterized thread. ParameterizedThreadStart param1 = new ParameterizedThreadStart(MethodToCall); Thread th1 = new Thread(param1); th1.Start(new ClassObject(StartingIndex, EndingIndex));

Question No 2:Using the multi-threaded code of Question 2, modify the code such that the Search function is accessed by one thread at a time and compare timing with results of Question 2(i.e. Make the method sequential).

Question No 3:Using C# Reflection, display all the method names that are available in the EntityFramework.dll (File has been uploaded on Slate\IPT\Lab Activity\EntityFramework.dll)

Question No 4:Create an ASMX Web Servicefor Currency conversion. Your web service will have a fixed list of currencies and their conversion ratesfrom US Dollar hardcoded. You have to provide the following functionalities:a.Get List of all Currencies and their rates against 1 US Dollar.b.A method to convert currency from one to another. Your method would include3 parameters, one for Source Currency, one for value to be converted, one for Destination Currency).

Question No 5:Create a Windows Form to consume the web serviceusing a Proxy Class.Generate proxy using thefollowing command: C:> wsdl /out:

Question No 6:Convert your ASMX Web Service into WCF Web Service and test the results through WCF Test Client.
