在上传或调整图像大小时检查图像的大小 [英] Check size of Image in the time of Uploading or resize the image

问题描述

我想在数据库中上传修复图片大小。或者在上传时调整图片大小.plz帮助我

I want to upload fix Size of image in the database.or resize Image on the time of uploading.plz help me

推荐答案

尝试以下方法： - < br $> b $ b

Try the following :-

string[] sizes = { "B", "KB", "MB", "GB" };
double len = new FileInfo(filename).Length;
int order = 0;
while (len >= 1024 && order + 1 < sizes.Length) {
    order++;
    len = len/1024;
}

string result = String.Format（{0：0。＃ ＃} {1}，len，sizes [order]）;

string result = String.Format("{0: 0.##} {1}", len, sizes[order]);

我在上传图片时对大小进行了一次验证，我使用HTTPHandler来避免回发。



但您的要求似乎有所不同，如果不是所需尺寸，您需要调整大小。你可以按照以下链接

I implemented once validation on size while uploading the image, I used a HTTPHandler to avoid postback.

But your requirement seems different, you want to resize if it not of required size. You can follow the below link
