Two classes with the same name can be created inside 2 different namespaces in a single program. Inside a namespace, no two classes can have the same name.
A class can also be declared inside namespace and defined outside namespace using the following syntax: CPP.
Classes are data types. They are an expanded concept of structures, they can contain data members, but they can also contain functions as members whereas a namespace is simply an abstract way of grouping items together. A namespace cannot be created as an object; think of it more as a naming convention.
You will need to do it "backwards"; list all the types in an assembly and then checking the namespace of each type:
using System.Reflection;
private Type[] GetTypesInNamespace(Assembly assembly, string nameSpace)
{
return
assembly.GetTypes()
.Where(t => String.Equals(t.Namespace, nameSpace, StringComparison.Ordinal))
.ToArray();
}
Example of usage:
Type[] typelist = GetTypesInNamespace(Assembly.GetExecutingAssembly(), "MyNamespace");
for (int i = 0; i < typelist.Length; i++)
{
Console.WriteLine(typelist[i].Name);
}
For anything before .Net 2.0 where Assembly.GetExecutingAssembly() is not available, you will need a small workaround to get the assembly:
Assembly myAssembly = typeof(<Namespace>.<someClass>).GetTypeInfo().Assembly;
Type[] typelist = GetTypesInNamespace(myAssembly, "<Namespace>");
for (int i = 0; i < typelist.Length; i++)
{
Console.WriteLine(typelist[i].Name);
}
You'll need to provide a little more information...
Do you mean by using Reflection. You can iterate through an assemblies Manifest and get a list of types using
System.Reflection.Assembly myAssembly = Assembly.LoadFile("");
myAssembly.ManifestModule.FindTypes()
If it's just in Visual Studio, you can just get the list in the intellisense window, or by opening the Object Browser (CTRL+W, J)
