i have xsd file using validate xml. problem error. error not thrown when run code in local machine. if run code in integration, error thrown.

dim strschemapath string = string.empty     dim xmlsettings xmlreadersettings = nothing     dim msstream memorystream = nothing     isxmlvalid = true     msstream = new memorystream(system.text.asciiencoding.utf8.getbytes(xmlrequest))     strschemapath = path.combine(system.appdomain.currentdomain.basedirectory, "xsd\input.xsd")     xmlsettings = new xmlreadersettings()     xmlsettings.validationtype = validationtype.schema     xmlsettings.schemas.add(nothing, strschemapath) 

there no issues access of file. there issue files copied in server path. can manage files in properties. changed file property copy , worked.
