Using the header file definition, the following file is used to implement these methods. As discussed in the previous section ‘void pointers’ are used to reference the collection elements. Void pointers are pointers which point to some arbitrary data that has no specific type. As a consequence...
Here, casting to the IDictionary interface can help as well.And although I’ve been comparing LINQ to XML and ExpandoObject in this post, these two approaches are not “rivals”. You can convert ExpandoObject to XElement and vice versa. For example, this is what the ExpandoObject to X...
A pointer to an object of typeDcan be safely cast toBorC. However, ifDis cast to point to anAobject, which instance ofAwould result? This would result in an ambiguous casting error. To get around this problem, you can perform two unambiguous casts. For example: ...

In C# 4.0, the compiler won’t complain about that code. The analogous code using System.Object won’t compile and requires some hacks on your own—reflection or adventurous casting—in order to work. var vs. dynamic The keywords var and dynamic are only apparently similar. Var indicates tha...
foreach(varpersonincontacts) ((IDictionary<String,Object>)person).Remove("Phone"); There are other useful methods in LINQ to XML likeSave()andLoad(). ForExpandoObjectyou need to write such methods yourself, but probably only once. Here, casting to theIDictionaryinterface can help as well. ...
In the C# 3.0 version, targetRange.Columns[1, Type.Missing] returns object, and that’s why the casting to Excel.Range is necessary. But in C# 4 and Visual Studio 2010 such calls are silently converted into dynamic ones. So, the type of the targetRange.Colum...
