本文介绍了如何验证在C#中的图像文件格式的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 有谁知道脚本来验证什么文件格式是给定的图像。目前,我填充图像对象,看着它的高度,宽度和分辨率。我没有看到任何具体的属性了这个对象,解释文件格式。 我想检查JPG,AI,PSD,高赫苏斯JPG,位图,和TIFF 下面是我目前的脚本: 保护布尔IsValidImage(HttpPostedFileBase文件,字符串文件名){ //验证图像是不超过648宽和648象素高图片imgPhoto = Image.FromStream(file.InputStream); 如果(imgPhoto.Width> 648)返回FALSE; 如果(imgPhoto.Height> 648)返回FALSE; 如果(imgPhoto.HorizontalResolution = 72 || imgPhoto.VerticalResolution = 72!)返回FALSE; 返回真; $ B提前 $ B} 感谢解决方案 使用 Image.RawFormat 。其结果是的imageformat 类,它可以针对的imageformat 的静态属性进行比较的一个实例。 请参阅 HTTP :了解更多详情//msdn.microsoft.com/en-us/library/system.drawing.imaging.imageformat.aspx Does anyone know the script to validate what the file format is for a given image. Currently i am populating an image object, looking at it's height, width, and resolution. I don't see any specific properties off of this object that explains the file format.I would like to check for jpg, AI, PSD, High Jes Jpg, Bitmap, and Tiff.here is my current script: protected bool IsValidImage(HttpPostedFileBase file, string fileName) { //verify that the image is no more than 648 wide and 648 pixels tall Image imgPhoto = Image.FromStream(file.InputStream); if (imgPhoto.Width > 648) return false; if (imgPhoto.Height > 648) return false; if (imgPhoto.HorizontalResolution != 72 || imgPhoto.VerticalResolution != 72) return false; return true; }Thanks in advance 解决方案 Use Image.RawFormat. The result is an instance of the ImageFormat class which can be compared against the static properties of ImageFormat.See http://msdn.microsoft.com/en-us/library/system.drawing.imaging.imageformat.aspx for more details. 这篇关于如何验证在C#中的图像文件格式的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 09-25 02:58
