"Could not find a part of the path" error message

Question

I am programming in c# and want to copy a folder with subfolders from a flash disk to startup.

Here is my code:

private void copyBat() {     try     {         string source_dir = "E:\\Debug\\VipBat";         string destination_dir = "C:\\Users\\pc\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup";          if (!System.IO.Directory.Exists(destination_dir))         {             System.IO.Directory.CreateDirectory(destination_dir);         }                 // Create subdirectory structure in destination             foreach (string dir in Directory.GetDirectories(source_dir, "*", System.IO.SearchOption.AllDirectories))         {             Directory.CreateDirectory(destination_dir + dir.Substring(source_dir.Length));                   }          foreach (string file_name in Directory.GetFiles(source_dir, "*.*", System.IO.SearchOption.AllDirectories))         {             File.Copy(file_name, destination_dir + file_name.Substring(source_dir.Length), true);         }     }     catch (Exception e)     {         MessageBox.Show(e.Message, "HATA", MessageBoxButtons.OK, MessageBoxIcon.Warning);     } } 

I got an error:

Could not find a part of the path E:\Debug\VipBat

Answer 1

The error is self explanatory. The path you are trying to access is not present.

string source_dir = "E:\\Debug\\VipBat\\{0}"; 

I'm sure that this is not the correct path. Debug folder directly in E: drive looks wrong to me. I guess there must be the project name folder directory present.

Second thing; what is {0} in your string. I am sure that it is an argument placeholder because folder name cannot contains {0} such name. So you need to use String.Format() to replace the actual value.

string source_dir = String.Format("E:\\Debug\\VipBat\\{0}",variableName); 

But first check the path existence that you are trying to access.

There's something wrong. You have written:

string source_dir = @"E:\\Debug\\VipBat\\{0}"; 

and the error was

Could not find a part of the path E\Debug\VCCSBat

This is not the same directory.

In your code there's a problem, you have to use:

string source_dir = @"E:\Debug\VipBat"; // remove {0} and the \\ if using @ 

or

string source_dir = "E:\\Debug\\VipBat"; // remove {0} and the @ if using \\
