C# Error CS0230 – Type and identifier are both required in a foreach statement

C# Compiler Error

CS0230 – Type and identifier are both required in a foreach statement

Reason for the Error

You will receive this error in your C# program when your foreach statement is poorly formatted.

For example, try to compile the below code snippet.

namespace DeveloperPubNamespace
{
    class Program
    {
     
        public static void Main()
        {
            int[] inputArray = new int[5] { 1, 2, 3, 4, 5 };
			// Results with Error
            foreach (int in inputArray)   
            {

            }
        }
    }
}

This program will result with the C# error code CS0230 because the foreach statement has invalid syntax and is missing the variable to be defined for accessing each index.

Solution

To fix the error code CS0230 in C#, you’ll need to correct the poorly formatted foreach loop as shown below.

namespace DeveloperPubNamespace
{
    class Program
    {
     
        public static void Main()
        {
            int[] inputArray = new int[5] { 1, 2, 3, 4, 5 };
            foreach (int index in inputArray)   
            {

            }
        }
    }
}
