Deserialize list of objects in C#

I Use JsonConvert to serialize an object and save it in a database.
This is a sample of the serialized string that I saved in database:

[{"matId":"1","value":"44"},{"matId":"2","value":"55"},{"matId":"4","value":"77"}]

Now when I get this string from database which has a lot of backslashes like this:

"[{"matId":"1","value":"44"},{"matId":"2","value":"55"},{"matId":"4","value":"77"}]"

And for this reason I can’t Deserialize it.

.Replace("\","") method doesn’t create any affect on this. I don’t know why.

Method 1

You have to use JsonConvert.Deserialize method.

Your json string is wrapped within square brackets ([]), hence it is interpreted as array. Therefore, you need to deserialize it to type collection of one class, for example let’s call it MyClass.

public class MyClass
{
    public int matId { get; set; }
    public int value { get; set; }
}

Here is Deserialize method.

var results=JsonConvert.DeserializeObject<List<MyClass>>(json);

Method 2

Backslashes represent serialized object.
You need to deserialize your List object.
You can try using Generics:

public List<T> Deserialize<T>(string path)
{
   return JsonConvert.DeserializeObject<List<T>>(path);
}
