在SharpDX.Direct2D1中使用DrawText时如何检测文本溢出？

using SharpDX;
using SharpDX.Direct2D1;
using SharpDX.DirectWrite;

// 创建Direct2D和DirectWrite的工厂对象
using (var factory = new Factory())
using (var writeFactory = new SharpDX.DirectWrite.Factory())
using (var renderTarget = new WindowRenderTarget(factory, new RenderTargetProperties(), new HwndRenderTargetProperties()))
{
    // 设置绘制区域的宽度
    float maxWidth = 200;

    // 创建文本格式对象
    var textFormat = new TextFormat(writeFactory, "Arial", 12);

    // 创建文本布局对象
    var textLayout = new TextLayout(writeFactory, "Hello, World!", textFormat, maxWidth, float.MaxValue);

    // 获取文本的度量信息
    var metrics = textLayout.Metrics;

    // 检测文本是否溢出
    bool isOverflow = metrics.Width > maxWidth;

    // 根据需要进行处理
    if (isOverflow)
    {
        // 文本溢出处理逻辑
        // ...
    }
    else
    {
        // 绘制文本
        renderTarget.BeginDraw();
        renderTarget.Clear(Color.White);
        renderTarget.DrawTextLayout(new Vector2(0, 0), textLayout, new SolidColorBrush(renderTarget, Color.Black));
        renderTarget.EndDraw();
    }
}
