C# 获取图像的旋转角度

public static int readPictureDegree(string path)
{
int rotate = 0;
using (var image = System.Drawing.Image.FromFile(path))
{
foreach (var prop in image.PropertyItems)
{
if (prop.Id == 0x112)
{
if (prop.Value[0] == 6)
rotate = 90;
if (prop.Value[0] == 8)
rotate = -90;
if (prop.Value[0] == 3)
rotate = 180;
prop.Value[0] = 1;
}
}
}
return rotate;
