C# Get type of fixed field in unsafe struct with reflection

I wish this helpful for you The Fixed Size Buffer's underlying type can be retrieved through the FixedBufferAttribute, which is applied on the fixed size buffer statement.
foreach (FieldInfo fi in typeof(MyStruct).GetFields(BindingFlags.Public | BindingFlags.Instance))
{
    var attr = fi.GetCustomAttributes(typeof(FixedBufferAttribute), false);
    if(attr.Length > 0)
        output += fi.Name + ": " + ((FixedBufferAttribute)attr[0]).ElementType + "\r\n";
    else
        output += fi.Name + ": " + fi.FieldType + "\r\n";
}
var type = typeof (MyStruct)
            .GetField("Field2")
            .GetCustomAttributes(typeof (FixedBufferAttribute), false)
            .Cast<FixedBufferAttribute>()
            .Single()
            .ElementType;
[StructLayout(LayoutKind.Sequential, Pack=1)]
public struct MyStruct
{
    public uint Field1;
    [FixedBuffer(typeof(sbyte), 10)]
    public <Field2>e__FixedBuffer0 Field2;
    public ulong Field3;
    // Nested Types
    [StructLayout(LayoutKind.Sequential, Size=10), CompilerGenerated, UnsafeValueType]
    public struct <Field2>e__FixedBuffer0
    {
       public sbyte FixedElementField;
    }
}

Initialise an unsafe fixed double array in struct

This might help you This question is a follow up from Marshalling C# structure to C++ Using StructureToPtr. I have the following struct: , Well the simple approach seems to work:
for (int i = 0; i < 3; i++)
{
    dynamicState.AngularVelocity[i] = array[i];
}
Marshal.Copy(array, 0, new IntPtr(dynamicState.AngularVelocity), array.Length);

will help you Suddenly the word 'extension method' crossed my mind. And yes, I have it working:
public static double[] CopyFixedDoubleArray(this Data data)
{
    unsafe
    {
        return new[] { data.Values[0], data.Values[1], data.Values[2] };
    }
}

hop of those help? Interoperating with C code, I was not able to directly cast a structure and I was forced to define an equivalent one in Go. The C function from libproc.h is , As per documentation
