For those who have no idea what I was talking about in my previous post (20060915).
That snip pet of code was showing how to remove an item on a collection based on a condition Person.IsTappable.
List.RemoveAll() is an alternative of this:
24 //...
25 for (int i = people.Count - 1; i >= 0; i--)
26 {
27 if (!((Person)people[i]).IsTappable)
28 {
29 people.RemoveAt(i);
30 }
31 }
32 //...
He may be good at sqratching, but he can't code!
But damn hes good at scratching!
Check out this test...
9 [Test]
10 public void ShouldRemoveUnTappablePeople()
11 {
12 List<Person> people = new List<Person>();
13 people.Add(new Person("Raven Riley", true));
14 people.Add(new Person("Jenna Haze", true));
15 people.Add(new Person("Lil' Kim", false));
16 people.Add(new Person("Beyonce", true));
17 people.Add(new Person("Missy Elliot", false));
18
19 Assert.AreEqual(5, people.Count);
20
21 people.RemoveAll(delegate(Person p) { return !p.IsTappable; });
22
23 Assert.AreEqual(3, people.Count);
24 Assert.AreEqual("Raven Riley", people[0].Name);
25 Assert.AreEqual("Jenna Haze", people[1].Name);
26 Assert.AreEqual("Beyonce", people[2].Name);
27 }
Ever created a utility class that maps a row to a property on an object you created?
Ever wondered how to convert this row item in to a type? (i.e. int, string, bool, etc...)
Ever created a big ass case statement to assign the damn data types to an item?
Well here is a snippet of code that converts a row item into a datatype based on the property it will be assigned to.
NYAHHHH!
37 //...
38 MethodInfo method = info.GetSetMethod();
39 try
40 {
41 method.Invoke(result, GetValue(method.GetParameters(), row[column]));
42 }
43 catch (Exception e)
44 {
45 throw new FormatException(info.Name + " is an incorrect data type." + info.Name, e);
46 }
47 //...
64 private static object[] GetValue(ParameterInfo[] parameterInfos, object parameterValue)
65 {
66 string parameterName = parameterInfos[0].ParameterType.Name;
67 if (parameterValue == DBNull.Value)
68 {
69 return new object[] {null};
70 }
71
72 Type conversionType = Type.GetType("System.Convert");
73 string methodName = "To" + parameterName;
74 MethodInfo conversionMethod =
75 conversionType.GetMethod(methodName, new Type[] {Type.GetType("System.Object")});
76 object val = conversionMethod.Invoke(conversionType, new object[] {parameterValue});
77 return new object[] {val};
78 }
Im so lazy to make a nhibernate.config that my app uses to load all its NHibernate settings. And since you can't use System.Configuration to load items on a assembly I had to find a way to load all these settings.
I just wanted to spike up NHibernate and verify everything with tests (NUnit). So here is a snippet of code that loads NHibernate setting using a Hashtable.
NYAHHHHHHHH!!!!
22 private void InitializeNHibernateConfig()
23 {
24 Hashtable configProperties = new Hashtable();
25
26 configProperties["hibernate.connection.provider"] =
27 "NHibernate.Connection.DriverConnectionProvider";
28 configProperties["hibernate.dialect"] = "NHibernate.Dialect.MsSql2000Dialect";
29 configProperties["hibernate.connection.driver_class"] =
30 "NHibernate.Driver.SqlClientDriver";
31 configProperties["hibernate.connection.connection_string"] =
32 "Server=GHETTOVM\\SQLEXPRESS;initial catalog=Northwind;Integrated Security=SSPI";
33
34 foreach (DictionaryEntry entry in configProperties)
35 {
36 config.SetProperty(entry.Key.ToString(), entry.Value.ToString());
37 }
38 }
