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)
{
}
}
}
}
