The json files are like the text below.

{

What I have tried:

Models.JsonLmodFileClass.LmodFileClass lmodObj = JsonConvert.DeserializeObject<Models.JsonLmodFileClass.LmodFileClass>(text);

classes defined below:

public class JsonLmodFileClass
{
    public class LmodFileClass

            public Lmod_File lmod_file { get; set; }
            public Rootobject()
            {
                lmod_file = new Lmod_File();

You've not explained what the error is exactly but you're trying to deserialize to a LmodFileClass but that class doesn't have the "lmod_file" property that's expected. Instead you've created the inner Rootobject class containing this, have you tried moving lmod_file to the parent LmodFileClass?

C#

public class LmodFileClass
{
   public Lmod_File lmod_file { get; set; }

   ...
}

For the Json shared by you, following is the C# model class:

C#

public class Param
{
    public object data { get; set; }
    public string name { get; set; }
    public string type { get; set; }
    public string value { get; set; }
}

public class Params
{
    public IList<Param> param { get; set; }
}

public class LmodFile
{
    public bool crlmod { get; set; }
    public string name { get; set; }
    public Params params { get; set; }
    public string path { get; set; }
}

public class ExampleRoot
{
    public LmodFile lmod_file { get; set; }
}

Usage:

C#

// ExampleRoot myDeserializedClass = JsonConvert.DeserializeObject<ExampleRoot>(myJsonResponse);
