copied!<p>In addition to the <a href="https://stackoverflow.com/questions/298830/split-string-containing-command-line-parameters-into-string-in-c/298990#298990">good and pure managed solution</a> by <a href="https://stackoverflow.com/users/27423/earwicker">Earwicker</a>, it may be worth mentioning, for sake of completeness, that Windows also provides the <a href="http://msdn.microsoft.com/en-us/library/bb776391.aspx" rel="nofollow noreferrer"><code>CommandLineToArgvW</code></a> function for breaking up a string into an array of strings:</p> <blockquote> <pre><code>LPWSTR *CommandLineToArgvW( LPCWSTR lpCmdLine, int *pNumArgs); </code></pre> <p>Parses a Unicode command line string and returns an array of pointers to the command line arguments, along with a count of such arguments, in a way that is similar to the standard C run-time argv and argc values.</p> </blockquote> <p>An example of calling this API from C# and unpacking the resulting string array in managed code can be found at, “<a href="http://intellitect.com/converting-command-line-string-to-args-using-commandlinetoargvw-api/" rel="nofollow noreferrer">Converting Command Line String to Args[] using CommandLineToArgvW() API</a>.” Below is a slightly simpler version of the same code:</p> <pre><code>[DllImport("shell32.dll", SetLastError = true)] static extern IntPtr CommandLineToArgvW( [MarshalAs(UnmanagedType.LPWStr)] string lpCmdLine, out int pNumArgs); public static string[] CommandLineToArgs(string commandLine) { int argc; var argv = CommandLineToArgvW(commandLine, out argc); if (argv == IntPtr.Zero) throw new System.ComponentModel.Win32Exception(); try { var args = new string[argc]; for (var i = 0; i < args.Length; i++) { var p = Marshal.ReadIntPtr(argv, i * IntPtr.Size); args[i] = Marshal.PtrToStringUni(p); } return args; } finally { Marshal.FreeHGlobal(argv); } } </code></pre>
