c#+编码后的服务器虚拟路径,.net c#如何将物理路径转换为虚拟路径

Below you can see the path that has been stored in the database and what i need it to look like. So I can use the path to change an image.

From the Database:

C:UsersAlphaDogDesktopAlumni RevisedAlumiTrackingSystemAlumiTrackingSystemAlumiTrackingSystemAlumiTrackingSystemimageVinceTulips.jpg

Needs to be changed to:

~/image/Vince/Tulips.jpg

Talk1:

Not clear, what does the first path means? Is it where your Website is hosted?

Talk3:

The first path is the root path where I saved it from the database. Then I need to get the path from Database to change the image but it cannot be change.

Talk4:

If I understand you correctly, you want to create a virtual directory that points to image folder.

Talk5:

I think the problem is that you don't have enough repetitions of AlumniTrackingSystem in your path. I think another 2 should do the trick.

Something like the following should do the trick. A little more code than the previous answer, but you know, sometimes I like to do things the hard way.

string path = @"C:UsersAlphaDogDesktopAlumni RevisedAlumiTrackingSystemAlumiTrackingSystemAlumiTrackingSystemAlumiTrackingSystemimageVinceTulips.jpg";

string[] splitPath = path.Split('\');

int start = 0;

foreach (string s in splitPath) {

if (s == "image")

break;

else

start++;

}

string virtualPath = "~/";

for (int i = start; start < splitPath.Length; start++) {

virtualPath += (i > start ? "/" : "") + splitPath[start];

}

i hope this is what you are looking for:

String RelativePath = AbsolutePath.Replace(Request.ServerVariables["APPL_PHYSICAL_PATH"], String.Empty);

it should work if your app phisical path is:

C:UsersAlphaDogDesktopAlumni RevisedAlumiTrackingSystemAlumiTrackingSystemAlumiTrackingSystemAlumiTrackingSystem
