Using API to work with BizForm files

BizForm files are exclusively stored in the file system. You can find them by default in following location:

<your project>/<site name>/BizFormFiles/<GUID>.<extension>

Example: ~/CorporateSite/BizFormFiles/21a23606-d038-4551-b02a-34626065ec11.jpg

Of course, you can change the location of BizForm files in CMS Site Manager -> Settings -> Select your web site -> Files section in “BizForm files folder” setting.

From database point of view, following information should be stored in one of your BizForm table columns:

<GUID>.<extension>/<orig_name>.<extension>

Example: 21a23606-d038-4551-b02a-34626065ec11.jpg/DocumentName.jpg

You can access the file using following URL:

~/CMSModules/BizForms/CMSPages/GetBizFormFile.aspx?filename=" + “<GUID>.<extension>” + "&sitename=" + SiteName

Example:

~CMSModules/BizForms/CMSPages/GetBizFormFile.aspx?filename=21a23606-d038-4551-b02a-34626065ec11.jpg&sitename=CorporateSite

Direct saving to the disk can be done with usage of DataHelper class:

// Path to BizForm files in file system.
string filesFolderPath = FormHelper.GetBizFormFilesFolderPath(this.SiteName);

// Get file size and path
string filePath = filesFolderPath + fileName;

// Ensure disk path
DirectoryHelper.EnsureDiskPath(filePath, UrlHelper.WebApplicationPhysicalPath);

DataHelper.SaveFileToDisk(filePath, postedFile.InputStream);


On the other hand you may need to retrieve the file from the disk. Here is an example:

string fileNameString = "605b0932-660c-43cf-b2e0-b5ccf519f75f.png/originalFileName.png";

BasicForm bf = new BasicForm();

string fileName = bf.GetGuidFileName(fileNameString);
string filePath = FormHelper.GetBizFormFilesFolderPath(CMSContext.CurrentSiteName) + fileName;

if (File.Exists(filePath))
{
FileStream stream = new FileStream(filePath, FileMode.Open, FileAccess.Read);

// Add attachment
Attachment attachment = new Attachment(stream, bf.GetFileNameForUploader(fileNameString));
}
