Web API , How to remove Slashes from web api json? - json

Question

Here is the Json Result :
"[{\"EmpId\":1,\"Full_Name\":\"Parth Dave\",\"City\":\"\"},{\"EmpId\":2,\"Full_Name\":\"Chirag\",\"City\":\"\"},{\"EmpId\":3,\"Full_Name\":\"Jay\",\"City\":\"\"}]"
Here is my code:
public string GetProducts()
{
var empQuery = from emp in objEmployeeEntities.Employees
select new EmployeeClass() { EmpId = emp.EmpId, Full_Name = emp.Full_Name };
var settings = new JsonSerializerSettings() { ContractResolver = new NullToEmptyStringResolver() };
var str = JsonConvert.SerializeObject(empQuery.ToList(), settings);
return str;
}
public class NullToEmptyStringValueProvider : IValueProvider
{
PropertyInfo _MemberInfo;
public NullToEmptyStringValueProvider(PropertyInfo memberInfo)
{
_MemberInfo = memberInfo;
}
public object GetValue(object target)
{
object result = _MemberInfo.GetValue(target);
if (_MemberInfo.PropertyType == typeof(string) && result == null) result = "";
return result;
}
public void SetValue(object target, object value)
{
_MemberInfo.SetValue(target, value);
}
}
public class NullToEmptyStringResolver : Newtonsoft.Json.Serialization.DefaultContractResolver
{
protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
{
return type.GetProperties()
.Select(p =>
{
var jp = base.CreateProperty(p, memberSerialization);
jp.ValueProvider = new NullToEmptyStringValueProvider(p);
return jp;
}).ToList();
}
}
