How to rotate a image in C# and VB.NET

To rotate a image in C# and VB.NET you can use the following snippet.

Sample C#

public enum RotateMode
{
	Ninetee = 0,
	OneHundretEighty = 1,
	TwoHundredSeventy = 2,
}

public static Image RotateImage(Image myImage, RotateMode myRotatemode)
{
	var ret = myImage;
	switch (myRotatemode)
	{
		case RotateMode.Ninetee:
			ret.RotateFlip(RotateFlipType.Rotate90FlipNone);
			break;
		case RotateMode.OneHundretEighty:
			ret.RotateFlip(RotateFlipType.Rotate180FlipNone);
			break;
		case RotateMode.TwoHundredSeventy:
			ret.RotateFlip(RotateFlipType.Rotate270FlipNone);
			break;
	}
	return ret;
}

Sample VB.NET

Public Enum RotateMode
	Ninetee = 0
	OneHundretEighty = 1
	TwoHundredSeventy = 2
End Enum

Public Shared Function RotateImage(myImage As Image, myRotatemode As RotateMode) As Image
	Dim ret = myImage
	Select Case myRotatemode
		Case RotateMode.Ninetee
			ret.RotateFlip(RotateFlipType.Rotate90FlipNone)
			Exit Select
		Case RotateMode.OneHundretEighty
			ret.RotateFlip(RotateFlipType.Rotate180FlipNone)
			Exit Select
		Case RotateMode.TwoHundredSeventy
			ret.RotateFlip(RotateFlipType.Rotate270FlipNone)
			Exit Select
	End Select
	Return ret
End Function
