C# Compiler Error
CS0178 – Invalid rank specifier: expected ‘,’ or ‘]’
Reason for the Error
You will receive this error in your C# code when the Array initialization is ill-formed with-in your program.
For example, lets try to compile the below code snippet.
namespace DeveloperPubNamespace
{
class Program
{
static void Main(string[] args)
{
int[][] inputArray = new int[10][1];
}
}
}The above code snippet will result with the error code CS0178 because the array inputArray declaration and initialization seems to be ill-formed.

Solution
To fix the error, ensure that the array initialization is correct and uses the right format when you initialize the 1-D, 2D or Multi-dimensional arrays in C#.
The error code CS0178 in the above program can be fixed by replacing the array initialization as shown below.
namespace DeveloperPubNamespace
{
class Program
{
static void Main(string[] args)
{
int[,] inputArray = new int[10, 1];
}
}
}
