在C#中根据控件名称获取控件实例的方法

Control[] controls = this.Controls.Find("yourControlName", true);
if (controls.Length > 0)
{
    Control foundControl = controls[0];
    // 使用foundControl
}

 
private Control FindControlByName(Control container, string name)
{
    foreach (Control c in container.Controls)
    {
        if (c.Name == name) return c;
        Control found = FindControlByName(c, name);
        if (found != null) return found;
    }
    return null;
}

 
Control myControl = FindControlByName(this, "yourControlName");
if (myControl != null)
{
    // 使用myControl
}

DependencyObject obj = LogicalTreeHelper.FindLogicalNode(this, "yourControlName");
if (obj != null)
{
    Control foundControl = obj as Control; // 或者根据具体类型进行转换，例如 Button、TextBox 等
    if (foundControl != null)
    {
        // 使用foundControl
    }
}

 
private DependencyObject FindDependencyObjectByName(DependencyObject parent, string name)
{
    int count = VisualTreeHelper.GetChildrenCount(parent);
    for (int i = 0; i < count; i++)
    {
        DependencyObject child = VisualTreeHelper.GetChild(parent, i);
        if (child is FrameworkElement && ((FrameworkElement)child).Name == name) return child;
        DependencyObject found = FindDependencyObjectByName(child, name);
        if (found != null) return found;
    }
    return null;
}

DependencyObject myControl = FindDependencyObjectByName(this, "yourControlName");
if (myControl != null)
{
    // 使用myControl，可能需要转换为具体类型，例如 Button、TextBox 等。
}
