system() to c# without calling cmd.exe

how to translate system("") to C# without c开发者_JAVA技巧alling cmd.exe? edit: i need to throw something like "dir"

If I correctly understood your question, you're looking for Process.Start.

See this example (from the docs):

// Opens urls and .html documents using Internet Explorer.
void OpenWithArguments()
{
    // url's are not considered documents. They can only be opened
    // by passing them as arguments.
    Process.Start("IExplore.exe", "www.northwindtraders.com");

    // Start a Web page using a browser associated with .html and .asp files.
    Process.Start("IExplore.exe", "C:\\myPath\\myFile.htm");
    Process.Start("IExplore.exe", "C:\\myPath\\myFile.asp");
 }

Edit

As you said you needed something like the "dir" command, I would suggest you to take a look at DirectoryInfo. You can use it to create your own directory listing. For example (also from the docs):

// Create a DirectoryInfo of the directory of the files to enumerate.
DirectoryInfo DirInfo = new DirectoryInfo(@"\\archives1\library");

DateTime StartOf2009 = new DateTime(2009, 01, 01);

// LINQ query for all files created before 2009.
var files = from f in DirInfo.EnumerateFiles()
           where DirInfo.CreationTimeUtc < StartOf2009
           select f;

// Show results.
foreach (var f in files)
{
    Console.WriteLine("{0}", f.Name);
}

As other folks noted, it's Process.Start. Example:

using System.Diagnostics;

// ...

Process.Start(@"C:\myapp\foo.exe");

I need to throw something like "dir"

If you need to run DIR, then you need to call cmd.exe as dir is internal to cmd.exe

Not sure if I understand your question. Are you looking for Process.Start?

Do you actually want the equivalent? You may not depending on what exactly you're trying to do.

For example calling copy from the command line has a C# equivalent itself, File.Copy, for dir there's a whole Directory class for getting info (these are a quick 2 out of thousands of examples). Depending on what you're after, C# most likely has a library/function for the specific command you're trying to run, usually a more robust method as well, instead of a global handler.

If the global "invoke this" is what you're after, then as the other answers suggest, using the System.Diagnostics.Process class is your best bet.

If you want to execute a command-line (cmd.exe) command, such as "dir" or "time" or "mkdir", pass the command as an argument to cmd.exe with the flag /C.

For example,

cmd.exe /C dir

or

cmd.exe /C mkdir "New Dir"
