问题：获取Text控件的内容

场景：Win+R启动运行框，需要设置或获取Edit控件中的内容

解决：

1.使用.NETFramework

UIA中有个TextPattern，里面有TextPatternRange，即可得到Text的内容

代码如下：

var desktop = AutomationElement.RootElement;
var condition_Name = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window); // 定义我们的查找条件，名字是test
var condition_Class = new PropertyCondition(AutomationElement.NameProperty, "运行"); // 定义我们的查找条件，名字是test
var window = desktop.FindFirst(TreeScope.Subtree, new AndCondition(condition_Class, condition_Name)); // 在桌面的子控件中查找第一个符合条件的窗体。

var condition_Edit = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit);
var textedit = window.FindFirst(TreeScope.Subtree, condition_Edit);

Console.WriteLine(textedit.Current.ProcessId);
Console.WriteLine(textedit.Current.ClassName);
Console.WriteLine(textedit.Current.NativeWindowHandle);

var clickPattern = (TextPattern)textedit.GetCurrentPattern(TextPattern.Pattern);
Console.WriteLine(clickPattern.DocumentRange.GetText(100));
Console.WriteLine(clickPattern.DocumentRange.GetText(100));

按道理，com接口应该与.NET Framework一致，即先获取TextPattern，然后获取TextPatternRange，获取Text，但是通过com接口获取到的TextPattern为Null

com的过程应该是：获取ValuePattern，使用SetValue或CurrentValue，设置或获取值

代码如下:

#获取文本框内容
desktop = AutomationElement.GetRootElement()

controlTypeProperty = PropertyCondition(UIAPropertyIds.UIA_ControlTypePropertyId, UIAControlTypeIds.UIA_WindowControlTypeId)
nameProperty = PropertyCondition(UIAPropertyIds.UIA_NamePropertyId, u"运行")
window = desktop.FindFirst(TreeScope.TreeScope_Descendants, AndCondition(controlTypeProperty, nameProperty))

print window.GetWindowPattern()

subControlTypeProperty = PropertyCondition(UIAPropertyIds.UIA_ControlTypePropertyId, UIAControlTypeIds.UIA_EditControlTypeId)
textedit = window.FindFirst(TreeScope.TreeScope_Descendants, subControlTypeProperty)

print textedit.element
print textedit.Current.GetProcessId()
print textedit.Current.GetClassName()
print hex(textedit.Current.GetNativeWindowHandle())

buttonProperty = PropertyCondition(UIAPropertyIds.UIA_NamePropertyId, u"确定")
button = window.FindFirst(TreeScope.TreeScope_Descendants, buttonProperty)

print textedit.GetValuePattern().CurrentValue
