Dictionary <string,string> map to an object using Automapper
Solution 1:
AutoMapper maps between properties of objects and is not supposed to operate in such scenarios. In this case you need Reflection magic. You could cheat by an intermediate serialization:
var data = new Dictionary<string, string>();
data.Add("Name", "Rusi");
data.Add("Age", "23");
var serializer = new JavaScriptSerializer();
var user = serializer.Deserialize<User>(serializer.Serialize(data));
And if you insist on using AutoMapper you could for example do something along the lines of:
Mapper
.CreateMap<Dictionary<string, string>, User>()
.ConvertUsing(x =>
{
var serializer = new JavaScriptSerializer();
return serializer.Deserialize<User>(serializer.Serialize(x));
});
and then:
var data = new Dictionary<string, string>();
data.Add("Name", "Rusi");
data.Add("Age", "23");
var user = Mapper.Map<Dictionary<string, string>, User>(data);
If you need to handle more complex object hierarchies with sub-objects you must ask yourself the following question: Is Dictionary<string, string>
the correct data structure to use in this case?
Solution 2:
This thread is a bit old, but nowadays there's how to do it on automapper without any configuration, as stated at official documentation:
AutoMapper can map to/from dynamic objects without any explicit configuration (...) Similarly you can map straight from Dictionary to objects, AutoMapper will line up the keys with property names.
Update:
The following code shows a working sample (with unit tests).
void Test()
{
var mapper = new MapperConfiguration(cfg => { }).CreateMapper();
var dictionary = new Dictionary<string, object>()
{
{ "Id", 1 },
{ "Description", "test" }
};
var product = mapper.Map<Product>(dictionary);
Assert.IsNotNull(product);
Assert.AreEqual(product.Id, 1);
Assert.AreEqual(product.Description, "test");
}
class Product
{
public int Id { get; set; }
public string Description { get; set; }
}
Solution 3:
As I've just stumbled upon this question I'd like to add this answer possible with the current version of AutoMapper (even if the original question is already pretty old):
public class MyConfig
{
public string Foo { get; set; }
public int Bar { get; set; }
}
var config = new MapperConfiguration(cfg => {});
var mapper = config.CreateMapper();
var source = new Dictionary<string, object>
{
["Foo"] = "Hello",
["Bar"] = 123
};
var obj = mapper.Map<MyConfig>(source);
obj.Foo == "Hello"; // true
