<p class="maodian"></p><h3>调用</h3>
<div class="jb51code"><pre class="brush:csharp;">ShellExecute(IntPtr.Zero, "open", UrlOrPath, null, null, ShowWindowCommands.SW_SHOWNORMAL);
</pre></div>
<p>UrlOrPath可为exe路径或者网页url(使用默认浏览器打开网页url)</p>
<p>使用ie打开网页url</p>
<div class="jb51code"><pre class="brush:csharp;">ShellExecute(NULL, "open", "IEXPLORE", "http://www.csdn.net", NULL, SW_SHOWMAXIMIZED);
</pre></div>
<p class="maodian"></p><h2>Process</h2>
<div class="jb51code"><pre class="brush:csharp;">using System.Diagnostics;
private static string Execute(string exePath, string parameters)
{
string result = String.Empty;
using (Process p = new Process())
{
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = exePath;
p.StartInfo.Arguments = parameters;
p.Start();
p.WaitForExit();
result = p.StandardOutput.ReadToEnd();
}
return result;
}
