我创建了一个CMS,使用
将所有图像上传到文件夹,将所有图像上传到文件夹file.SaveAs(Server.MapPath("../images/") + advertID.ToString + "_" + i.ToString + fileExt)
现在,所有图像都已保存,我忘记了它创建缩略图。 :(
我需要一次阅读所有图片并创建缩略图,
myimg = System.Drawing.Image.FromFile(imgFileName)
myimg = myimg.GetThumbnailImage(154, 94, Nothing, IntPtr.Zero)
myimg.Save(Server.MapPath("../Content/") + "Thumb_" + imgFileName, myimg.RawFormat)
我需要这个才能快速运作。我似乎不知道如何逐个阅读这些图像名称。
提前致谢。

this的略微修改版本:
public void createThumbnails(string sourceDir)
{
//Process the list of files found in the directory.
string [] fileEntries = Directory.GetFiles(sourceDir);
foreach(string fileName in fileEntries)
{
//Do resizing here.
myimg = System.Drawing.Image.FromFile(fileName);
myimg = myimg.GetThumbnailImage(154, 94, Nothing, IntPtr.Zero);
myimg.Save(Server.MapPath("../Content/") + "Thumb_" + fileName, myimg.RawFormat);
}
}
这样称呼:
createThumbnails("C:\Path\To\Images");
*编辑:使用converter工具等效的VB.NET:
Public Sub createThumbnails(ByVal sourceDir As String)
Dim fileEntries As String() = Directory.GetFiles(sourceDir)
For Each fileName As String In fileEntries
myimg = System.Drawing.Image.FromFile(fileName)
myimg = myimg.GetThumbnailImage(154, 94, [Nothing], IntPtr.Zero)
myimg.Save((Server.MapPath("../Content/") & "Thumb_") + fileName, myimg.RawFormat)
Next
End Sub
