解决方案
这段代码正在为我工作，并获得chrome的活动标签的URL
Process [] procsChrome = Process.GetProcessesByName（chrome）;
foreach（procsChrome中的Process chrome）
{
// chrome进程必须有一个窗口
if（chrome.MainWindowHandle == IntPtr.Zero）
{
继续;
}
//找到自动化元素
AutomationElement elm = AutomationElement.FromHandle（chrome.MainWindowHandle）;
AutomationElement elmUrlBar = elm.FindFirst（TreeScope.Descendants，
new PropertyCondition（AutomationElement.NameProperty，Address and search bar））;
//如果可以找到它，从URL栏获得值
if（elmUrlBar！= null）
{
AutomationPattern [] patterns = elmUrlBar。 GetSupportedPatterns（）;
if（patterns.Length> 0）
{
ValuePattern val =（ValuePattern）elmUrlBar.GetCurrentPattern（patterns [0]）;
Console.WriteLine（Chrome URL found：+ val.Current.Value）;
listbox.Items.Add（val.Current.Value）;
}
}
}

this code is working for me and get URL of active tab of chrome
Process[] procsChrome = Process.GetProcessesByName("chrome");
foreach (Process chrome in procsChrome)
{
// the chrome process must have a window
if (chrome.MainWindowHandle == IntPtr.Zero)
{
continue;
}
// find the automation element
AutomationElement elm = AutomationElement.FromHandle(chrome.MainWindowHandle);
AutomationElement elmUrlBar = elm.FindFirst(TreeScope.Descendants,
new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));
// if it can be found, get the value from the URL bar
if (elmUrlBar != null)
{
AutomationPattern[] patterns = elmUrlBar.GetSupportedPatterns();
if (patterns.Length > 0)
{
ValuePattern val = (ValuePattern)elmUrlBar.GetCurrentPattern(patterns[0]);
Console.WriteLine("Chrome URL found: " + val.Current.Value);
listbox.Items.Add(val.Current.Value);
}
}
}
