Hello- Please help me with the following questions, if possible, please also provide some explanations--thanks in advance: 1) Assuming that "valid connection string" is a valid connection string, what will be the output of the following code? If the code cannot compile, please state why. the same rules apply to this question as for the one above using(SqlConnection sqlConn = new SqlConnection("valid Connection string")) { System.Diagnostics.Debug.WriteLine("Opening a connection"); sqlConn.Open(); System.Diagnostics.Debug.WriteLine("Connection Opened"); sqlConn.Close(); System.Diagnostics.Debug.WriteLine("Connection Closed"); } if(sqlConn == null) System.Diagnostics.Debug.WriteLine("Connection State is NULL"); else System.Diagnostics.Debug.WriteLine("Connection State:" + sqlConn.ConnectionState); 2)The following code needs to generate a string of 1000 alternating '+' and '-' characters Rewrite this code to make it more efficient (Note: You can use different data types than the ones present) string htmlOutput = string.Empty; for(int itemIndex = 0; itemIndex < 1000; itemIndex++) { if( itemIndex % 2 == 0) htmlOutput += "+"; else htmlOutput += "-"; } 3)Assuming that CustomException is defined, what will be the output of the following code? try { throw new CustomException("Something went wrong"); } catch(Exception ex) { System.Diagnostics.Debug.WriteLine("Generic Exception has been triggered"); } catch(CustomException ex) { System.Diagnostics.Debug.WriteLine("Custom Exception has been triggered"); } 4) What will be the difference in behavior between the lines marked 'a' and 'b' during runtime? (Assume that CustomClass is a defined class) object objClass = new object(); CustomClass myClass1 = objClass as CustomClass; //a CustomClass myClass2 = (CustomClass)objClass; //b 5) Assuming you have the following class: public class MyClass { public MyClass() { } public string DoNothing(string someParameter) { System.Diagnostics.Debug.WriteLine(someParameter); } } How would you call the DoNothing function asynchronously and provide a callback? 6) What is the difference between a Monitor and a Semaphore? 7) Architectural Question: If you have pages that perform heavy DB or File I/O, what could be
