# PrimitiveStaticDataGenerator
[](https://www.nuget.org/packages/PrimitiveStaticDataGenerator)
## Usage
user code:
```cs
using System;
using PrimitiveStaticDataGenerator;
namespace MyCode
{
public partial class UserClass
{
[return: PrimitiveStaticData(1, 2, 3, 4, 5)]
public static partial ReadOnlySpan Int();
[return: PrimitiveStaticData('A', 'B', 'C')]
public static partial ReadOnlySpan Char();
}
}
```
generated code:
```cs
using System;
using PrimitiveStaticDataGenerator;
using System.Runtime.InteropServices;
using System.Runtime.CompilerServices;
namespace MyCode
{
public partial class UserClass
{
public static partial ReadOnlySpan Int()
{
ReadOnlySpan span;
if (BitConverter.IsLittleEndian)
{
span = new byte[] { 1, 0, 0, 0, 2, 0, 0, 0, 3, 0, 0, 0, 4, 0, 0, 0, 5, 0, 0, 0 };
}
else
{
span = new byte[] { 0, 0, 0, 1, 0, 0, 0, 2, 0, 0, 0, 3, 0, 0, 0, 4, 0, 0, 0, 5 };
}
return MemoryMarshal.CreateReadOnlySpan(ref Unsafe.As(ref MemoryMarshal.GetReference(span)), 5);
}
public static partial ReadOnlySpan Char()
{
ReadOnlySpan span;
if (BitConverter.IsLittleEndian)
{
span = new byte[] { 65, 0, 66, 0, 67, 0 };
}
else
{
span = new byte[] { 0, 65, 0, 66, 0, 67 };
}
return MemoryMarshal.CreateReadOnlySpan(ref Unsafe.As(ref MemoryMarshal.GetReference(span)), 3);
}
}
