I set to copy a text file from a module to SharePoint server directory

<?xml version="1.0" encoding="utf-8"?>
 <Elements xmlns="http://schemas.microsoft.com/sharepoint/">
   <Module Name="MyModule">
    <File IgnoreIfAlreadyExists="TRUE" Path="MyModule\newFile.txt" Url="MyModule/newFile.txt" />
  </Module>
</Elements>

After that, in featureActivated, I am going to get the file by this code:

                try
                {
                    SPFile newFile = myWeb.GetFile(properties.Definition.RootDirectory + "\\MyModule\\newFile.txt");
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }

I got this exception : “Value does not fall within the expected range”. What is wrong with me?

The SPWeb.GetFile Method (String) get file from SharePoint site, the properties.Definition.RootDirectory return the local path, you will get the exception.

I suggest you upload the file into document library like "Site Assets" in root web, then get file in feature receiver.

Example code:

Elements.xml

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <Module Name="MyModule" Url="SiteAssets" RootWebOnly="TRUE">
    <File IgnoreIfAlreadyExists="TRUE" Type="GhostableInLibrary" Path="MyModule\newFile.txt" Url="newFile.txt" />
  </Module>
</Elements>

Feature Receiver

try
{
    SPWeb myWeb = SPContext.Current.Site.RootWeb;
    SPFile newFile = myWeb.GetFile(myWeb.ServerRelativeUrl + "/SiteAssets/newFile.txt");
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}

  • I am not sure about SiteAssets. There is no warranty that this document library exists in every site that I am going to activate my feature. What is your idea? – hossein hashemian Nov 05 '19 at 18:13
  • We can only upload the file into "SiteAssets" in root web, and get file from the root web. Check my updated reply. – LZ_MSFT Nov 06 '19 at 02:29
  • You mean, we can be sure of existing "SiteAssets" document library in root web every site collection we are working on? – hossein hashemian Nov 06 '19 at 18:18
  • You can use PowerShell to check if this library in root web every site collection, – LZ_MSFT Nov 07 '19 at 01:50
