If you know that your app is going to be run from the same place every time (like a folder) you can call the <a href="https://msdn.microsoft.com/en-us/library/system.io.directory.getcurrentdirectory%28v=vs.110%29.aspx?f=255&amp;MSPPError=-2147217396" rel="nofollow">GetCurrentDirectory()</a> method. This will return a string of the current directory that your app is running from.

<pre><code>String pwd = GetCurrentDirectory(); //Contains something like C:\Users\Daedric\TestApp\
String finalString = Path.Combine(pwd, "test.txt"); //As per Corak
</code></pre>

Besides above answer, following example can help you understand how <a href="http://www.dotnetperls.com/path" rel="nofollow">Path</a> works: 

<pre><code>class Program
 {
 static void Main()
 {
 string[] pages = new string[]
 {
 "cat.aspx",
 "really-long-page.aspx",
 "test.aspx",
 "invalid-page",
 "something-else.aspx",
 "Content/Rat.aspx",
 "http://dotnetperls.com/Cat/Mouse.aspx",
 "C:\\Windows\\File.txt",
 "C:\\Word-2007.docx"
 };
 foreach (string page in pages)
 {
 string name = Path.GetFileName(page);
 string nameKey = Path.GetFileNameWithoutExtension(page);
 string directory = Path.GetDirectoryName(page);
 //
 // Display the Path strings we extracted.
 //
 Console.WriteLine("{0}, {1}, {2}, {3}",
 page, name, nameKey, directory);
 }
 }
 }
</code></pre>

Sample output would be like this:

Input C:\Windows\File.txt 
GetFileName: File.txt 
GetDirectoryName: C:\Windows

You need start file from your app folder?

<pre><code>Application.StartupPath
</code></pre>

for start file

<pre><code>Process.Start(Application.StartupPath + @"\test.txt");
</code></pre>

blocks|key|96563|text|GetCurrentDirectory不是使用的正确方法，因为在应用程序运行时，返回值可能会更改。只需在控制台应用程序中运行以下程序就可以看到这一点：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|96564|Console.WriteLine(Directory.GetCurrentDirectory());
Directory.SetCurrentDirectory(@"c:\temp\");
Console.WriteLine(Directory.GetCurrentDirectory());|code-block|syntax|javascript|96565|您可以使用以下方法给出程序集的位置：|96566|Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location)|96567|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

GetCurrentDirectory is not the correct method to use as the return value can change while you application is running. You can see this by simply running the following in a console app:

<pre><code>Console.WriteLine(Directory.GetCurrentDirectory());
Directory.SetCurrentDirectory(@"c:\temp\");
Console.WriteLine(Directory.GetCurrentDirectory());
</code></pre>

You can use the following to give you the assembly location: 

<pre><code>Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location)
</code></pre>

So I'm learning how to develop software and I'm running into a problem. When I create a form in Visual Studio and have it open a document or open something else when I click a button I have it pointing here:

<pre><code>C:\User\MyName\Documents\TestApp\test.txt
</code></pre>

What I want to know is how do I get it to where the program just looks at TestApp folder vs going through the C: Drive? Say all the files are needed for the program to run are located in the TestApp folder.

How to run a program in the same folder?
