Get sharepoint list item attachment programmatically

Here is steps to get sharepoint list item attachment programmatically.

- Follow the steps to insert new item into your sharepoint list.

- Create new instance of site with your current application
using (SPSite site = new SPSite(SPContext.Current.Web.Url.ToString()))
{

- Create new web instance and open web for current application
using (SPWeb web = site.OpenWeb())
{

- Create new list object and get your list
SPList SPLData = web.Lists["Your List Name"];

- Create new query object to hold query which fetches list item of the list
SPQuery SPMyQuery = new SPQuery();

- Assign query with value to it in ID field of the list item
SPMyQuery.Query = string.Format(“<Where >  < Eq >  < FieldRef Name='ID' / >  < Value Type='Counter' > {0} < /Value >  < /Eq >  < /Where >”,1);

- Assign query to list and get item on the basis of the query build above
SPListItemCollection common = SPLData.GetItems(SPMyQuery);

- Check whether list collection contains result of the query, if contains item the proceed to update value of the list item
if (common.Count > 0)
{
SPListItem mylistItem = common[0];
string[] _Str_Attachments = GetAttachmentCollection(mylistItem);

- You can assign attachment collection with grid and if you want to give link to the attachment filename, on each file name with anchor link put following code for href of anchor.
string.Format("/Lists/{0}/Attachments/{1}/{2}", "Your List Name”,1,”FileName”);

}
}
}

- Get sharepoint list item attachment collection
public string[] GetAttachmentCollection(SPListItem item)
{
string FileNames = String.Empty;
if (item.Attachments.Count > 0)
{
string[] _Str_File_Name = new string[item.Attachments.Count];
for (int i = 0; i < item.Attachments.Count; i++)
{
SPFile file = item.ParentList.ParentWeb.GetFile(item.Attachments.UrlPrefix + item.Attachments[i].ToString());
_Str_File_Name[i]= file.Name;
}
return _Str_File_Name;
}
return null;
}


-That’s it for fetching attachments for existing item of sharepoint list.
