C# Compiler Error
CS0547 – ‘property’ : property or indexer cannot have void type
Reason for the Error
You will get this error in your C# code when you have a property or indexer with a return type of void.
For example, let’s compile the below C# program
using System;
namespace DeveloperPublishConsoleCore
{
public class Employee
{
public void Id
{
get
{
// return 0;
}
}
}
internal class Program
{
static void Main(string[] args)
{
Console.WriteLine("DeveloperPublish Hello World!");
}
}
}You will receive the error code CS0547 because the class Employee contains a property Id that has a return type void.

Solution
In C#, void is not a valid return type for a property or indexer. You can fix this error in your C# program by ensuring that a valid return type is provided for the property.
using System;
namespace DeveloperPublishConsoleCore
{
public class Employee
{
public int Id
{
get
{
return 0;
}
}
}
internal class Program
{
static void Main(string[] args)
{
Console.WriteLine("DeveloperPublish Hello World!");
}
}
}
