C# Compiler Error
CS0188 – The ‘this’ object cannot be used before all of its fields are assigned to
Reason for the Error
You will receive this error when you are using struct in your C# code and have not initialized the backing fields in the constructor. You might be initializing the property which would be causing this error. All the fields in a struct should be assigned by the constructor.
For example, try to compile the below code snippet.
using System;
namespace DeveloperPubNamespace
{
public struct Employee
{
private int _id ;
private string _name;
public int Id
{
get { return this._id; }
set { this._id = value; }
}
public Employee(int Id, string Name)
{
this.Id = Id;
}
}
class Program
{
static void Main(string[] args)
{
}
}

Solution
To fix the error, you will need to initialize all the backing fields of the property instead of initializing the property itself as shown below.
using System;
namespace DeveloperPubNamespace
{
public struct Employee
{
private int _id ;
private string _name;
public int Id
{
get { return this._id; }
set { this._id = value; }
}
public Employee(int Id, string Name)
{
_id = Id;
_name = Name;
}
}
class Program
{
static void Main(string[] args)
{
}
}
}
