AnalysisStatusBase.Successful 属性
返回分析操作结果的布尔摘要。
命名空间： System.Windows.Ink.AnalysisCore
程序集： IACore（在 IACore.dll 中）
语法
声明
Public ReadOnly Property Successful As Boolean
用法
Dim instance As AnalysisStatusBase
Dim value As Boolean
value = instance.Successful
public bool Successful { get; }
public:
property bool Successful {
bool get ();
}
/** @property */
public boolean get_Successful()
public function get Successful () : boolean
属性值
类型：System.Boolean
如果分析操作完成而没有任何警告，则为 true。如果至少发生一个警告，则为 false。
示例
下面的示例演示如何在墨迹分析之后查找警告。用 Afrikaans 识别器（可能您还未安装该识别器）执行分析时，分析将失败，并返回 InkRecognizerInitializationFailed 警告。这意味着 Successful 属性为 false。在此简单示例中，只是使用 Debug.WriteLine 将调试信息直接发送到输出窗口。
