C# – Getting the path of a file using fileupload control

asp.netcfile upload

I am using a fileupload control to display the contents of a text file in a textbox..if i use this

<asp:FileUpload ID="txtBoxInput" runat="server" Text="Browse" />

string FilePath = txtBoxInput.PostedFile.FileName;

it will get only the file name like bala.txt.i need like this D:\New Folder\bala.txt

Instead of fileupload control i have used textbox to get the path like this D:\New Folder\bala.txt

<asp:TextBox ID="txtBoxInput" runat="server" Width="451px"></asp:TextBox>

string FilePath = txtBoxInput.Text;

But i need browse button instead of textbox to get the path…Any Suggestion??

EDIT:My button click event

protected void buttonDisplay_Click(object sender, EventArgs e)
{
    string FilePath = txtBoxInput.PostedFile.FileName;
    if (File.Exists(FilePath))
    {
        StreamReader testTxt = new StreamReader(FilePath);
        string allRead = testTxt.ReadToEnd();
        testTxt.Close();
    }
}

You can get the file name and path from FileUpload control only when you are in debug mode but when you deployed your app. in server then you cant because that is your client address which you are trying to access by server side code.

protected void Button1_Click(object sender, EventArgs e)
{
    string filePath,fileName;
    if (FileUpload1.PostedFile != null)
    {
        filePath = FileUpload1.PostedFile.FileName; // file name with path.
        fileName = FileUpload1.FileName;// Only file name.
    }
}

If you really want to change properties or rename client file then you can save file on server on temp folder then you can do all thing which you want.

C# – Should ‘using’ directives be inside or outside the namespace

There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs:

// File1.cs
using System;
namespace Outer.Inner
{
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now imagine that someone adds another file (File2.cs) to the project that looks like this:

// File2.cs
namespace Outer
{
    class Math
    {
    }
}

The compiler searches Outer before looking at those using directives outside the namespace, so it finds Outer.Math instead of System.Math. Unfortunately (or perhaps fortunately?), Outer.Math has no PI member, so File1 is now broken.

This changes if you put the using inside your namespace declaration, as follows:

// File1b.cs
namespace Outer.Inner
{
    using System;
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now the compiler searches System before searching Outer, finds System.Math, and all is well.

Some would argue that Math might be a bad name for a user-defined class, since there's already one in System; the point here is just that there is a difference, and it affects the maintainability of your code.

It's also interesting to note what happens if Foo is in namespace Outer, rather than Outer.Inner. In that case, adding Outer.Math in File2 breaks File1 regardless of where the using goes. This implies that the compiler searches the innermost enclosing namespace before it looks at any using directive.

Display only file name in FileUpload control

I'm pretty sure that isn't possible. You cannot set the value inside of the FileUpload control's textbox at anytime, via server side or client side script.
