I need to detect if an object was created anonymously like new{name=value,}
if it is an AnonymousType, it should add it's properties names/values into a
Dictionary<string,object>
This is what I hacked together myself:
var name="name";
var obj = new { name = new object(), };
var lookup = new Dictionary<string,object>();
if(obj.GetType().Name.StartsWith("<>f__AnonymousType"))
{
foreach (var property in obj.GetType().GetProperties())
{
lookup[property.Name] = property.GetValue(obj, null);
}
}
else
{
lookup[name]=obj;
}
I was wondering if there is a better/faster way of detecting AnonymousTypes, or if there is a better/faster way to dump an object's properties names/values into a
Dictionary<string,object>
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
To get all the properties of an object, with its values into a Dictionary
, you can couple the power of Linq to Objects with Reflection.
You can use the Enumerable.ToDictionary method:
var dic = obj.GetType()
.GetProperties()
.ToDictionary(p => p.Name, p=> p.GetValue(obj, null));
This will return you a Dictionary<string, object>
.
Use the new collection object initializer syntax instead of an anonymous type:
var obj = new Dictionary<string, object>()
{
{ "Name", t.Name },
{ "Value", t.Value }
};
Detecting an anonymous type is a little hard; not-least it depends on the language! VB anon-types don't look the same as C# anon-types. I'd be dubious about logic that acts vary differently on anon-types. You might check for [CompilerGenerated]
, but note that it doesn't just mean "anonymous type" - there are others that do this.
Personally, I wouldn't distinguish in this scenario.
