C# Compiler Error
CS0170 – Use of possibly unassigned field ‘field’
Reason for the Error
You will receive this error when C# compiler detected a field with-in a structure that was used without being initialized.
For example, the below code snippet will result with the error because the struct logData.Level was not initialized.
using System;
namespace ConsoleApp2
{
public struct Log
{
public int Level ;
}
class Program
{
public static void Main()
{
Log logData;
Console.WriteLine(logData.Level);
}
}
}

Solution
Ensure that you identify and initialize the struct variable that was uninitialized before its usage. The above code can be fixed as follows.
using System;
namespace ConsoleApp2
{
public struct Log
{
public int Level ;
}
class Program
{
public static void Main()
{
Log logData;
logData.Level = 1;
Console.WriteLine(logData.Level);
}
}
}
