问题描述
复制/转换一个数组的快速方法
Color32 []
值到 byte []
buffer?
Color32
是Unity 3D的结构,包含 4个字节,R,G,B和A
。
我想要完成的是将渲染的图像从unity通过管道发送到另一个应用程序( Windows Forms
)。目前我使用的代码:
What would be a fast method to copy/convert an array
of Color32[]
values to a byte[]
buffer?
Color32
is a struct from Unity 3D containing 4 bytes, R, G, B and A respectively
.
What I'm trying to accomplish is to send the rendered image from unity through a pipe to another application (Windows Forms
). Currently I'm using this code:
private static byte[] Color32ArrayToByteArray(Color32[] colors)
{
int length = 4 * colors.Length;
byte[] bytes = new byte[length];
IntPtr ptr = Marshal.AllocHGlobal(length);
Marshal.StructureToPtr(colors, ptr, true);
Marshal.Copy(ptr, bytes, 0, length);
Marshal.FreeHGlobal(ptr);
return bytes;
}
谢谢对不起,我是StackOverflow的新人。

推荐答案
我最后使用这段代码:
private static byte[] Color32ArrayToByteArray(Color32[] colors)
{
if (colors == null || colors.Length == 0)
return null;
int lengthOfColor32 = Marshal.SizeOf(typeof(Color32));
int length = lengthOfColor32 * colors.Length;
byte[] bytes = new byte[length];
GCHandle handle = default(GCHandle);
try
{
handle = GCHandle.Alloc(colors, GCHandleType.Pinned);
IntPtr ptr = handle.AddrOfPinnedObject();
Marshal.Copy(ptr, bytes, 0, length);
}
finally
{
if (handle != default(GCHandle))
handle.Free();
}
return bytes;
}
这足够满足我的需要。
