C# Error
CS9050 – A ref field cannot refer to a ref struct.
Reason for the Error & Solution
A ref field cannot refer to a ref struct.
The compiler does not support the ref modifier on a field within a struct (to declare a stack-allocated field) of a type already declared stack-allocated (ref struct).
Example
The following sample generates CS9050:
// CS9050.cs (0,0)
ref struct Color
{
public float r, g, b;
}
ref struct Group
{
public ref Color color;
}
To correct this error
In this example, it is most likely a typo to have included a ref modifier on a field of a ref struct type within the declaration of a ref struct. Removing the ref modifier corrects this error.
ref struct Color
{
public float r, g, b;
}
ref struct Group
{
public Color color;
}
