Compiler Error CS0150
A constant value is expected
A variable was found where a constant was expected. For more information, see switch.
The following sample generates CS0150:
C#
// CS0150.cs
namespace MyNamespace
{
public class MyClass
{
public static void Main()
{
int i = 0;
int j = 0;
switch(i)
{
case j: // CS0150, j is a variable int, not a constant int
// try the following line instead
// case 0:
}
}
}
}
This error is also produced when an array size is specified with a variable value and initialized with an array initializer. To remove the error, initialize the array in a separate statement or statements.
C#
// CS0150.cs
namespace MyNamespace
{
public class MyClass
{
public static void Main()
{
int size = 2;
double[] nums = new double[size] { 46.9, 89.4 }; //CS0150
// Try the following lines instead
// double[] nums = new double[size];
// nums[0] = 46.9;
// nums[1] = 89.4;
}
}
}
