The following C# sample code demonstrates how to read a file in hex mode:
ilonWebRef.Item_Coll itemColl = new ilonWebRef.Item_Coll();
itemColl.xSelect =
"//*[@xsi:type=\"FileSystem\"][UCPTname=\"/root/data/myfile.txt\"][UCPTfileFormat=\"hex\"]";
ilonWebRef.Item_DataColl readResp = ilon.Read(itemColl);
if (readResp.UCPTfaultCount > 0)
MessageBox.Show(readResp.fault.faultstring);
else
String str = (readResp.Item[0] as ilonWebRef.FileSystem_Data).Value;
Note: You can read and write file system data that includes new line characters. For example, using
the Read function on the following file system data:
/data/writetest.txt
text
Hello
World
!
