不支持URI格式

Question

I am new and I try to open a file. Here is code:

string path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
string filenamelocation = System.IO.Path.Combine(path, "Fix_DeltaPro.exe");
System.Windows.MessageBox.Show(""+filenamelocation+"");
using (FileStream stram = File.Open(filenamelocation, FileMode.Open)) ;

But have little error : "URI formats are not supported. " Help me please :)

Answer 1

The CodeBase is a Uri where the assembly was found. This can a file file:// , a web location http:// , or other locations .

In the instance of a file get the AbsolutePath for the Uri.

var codeBaseUri = new Uri(Assembly.GetExecutingAssembly().CodeBase);
var path = Path.GetDirectoryName(codeBaseUri.AbsolutePath);
var filenamelocation = Path.Combine(path, "Fix_DeltaPro.exe");

MessageBox.Show(filenamelocation);
using (var stream = File.Open(filenamelocation, FileMode.Open)) ;

Since the CodeBase can be loaded from difference places use the Assembly.Location to get the location where the assembly was loaded from disk.

var path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
var filenamelocation = Path.Combine(path, "Fix_DeltaPro.exe");

MessageBox.Show(filenamelocation);
using (var stream = File.Open(filenamelocation, FileMode.Open)) ;
