C# Xamarin表单自定义单元格货币格式？

我有一个自定义的FiancialCell，它可以工作，但不能格式化为货币。是否有其他方法更改绑定格式，使其为$

    public FinancialCell()
    {
          .......

        //Set the bindings to the FinancialRow object to be bound to this
        lblTitle.SetBinding(Label.TextProperty, "Title");

        ///Why does this not format to $ when displayed?
        lblValue.SetBinding(Label.TextProperty, "Value", stringFormat: "C");


        this.View = stack;
    }

改用

“{0:C}”

，它就会工作

以下是与修复程序集成的示例，仅为完整起见：-

    public FinancialCell()
    {
          .......

        //Set the bindings to the FinancialRow object to be bound to this
        lblTitle.SetBinding(Label.TextProperty, "Title");

        ///Why does this not format to $ when displayed?
        lblValue.SetBinding(Label.TextProperty, "Value", stringFormat: "{0:C}");


        this.View = stack;
    }
