Wpf 动态添加的DataTemplate-转换器can的StaticResource'；找不到

我正在使用以下代码向GridView动态添加列：

public void AddGridViewColumns()
{
    GridView view = (GridView)_myListView.View;
    GridViewColumn column = BuildGridViewColumn(1);
    view.Columns.Add(column);
}

public virtual GridViewColumn BuildGridViewColumn(int blockIndex)
{
    string templateXaml = string.Format(
        @"<DataTemplate
            xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation""
            xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml""
            xmlns:local=""clr-namespace:Pse.MyTest;assembly=MyTest"">
            <DataTemplate.Resources>
                <local:BlockToBrushConverter
                    x:Key=""_blockToBrushConverter"" />
            </DataTemplate.Resources>
            <TextBlock
                Style=""{{StaticResource _gridViewCenterItemStyle}}""
                Text=""{{Binding Path=Block{0}.ConditionLabel}}""
                Foreground=""{{Binding Path=Block{0}, Converter={{StaticResource _blockToBrushConverter}}}}"" />
        </DataTemplate>",
        blockIndex);
    System.Diagnostics.Debug.Print(templateXaml);
    GridViewColumn column = new GridViewColumn();
    column.Header = string.Format("Block {0}", blockIndex);
    column.CellTemplate = (DataTemplate)XamlReader.Parse(templateXaml);
    return column;
}

如果我删除Forecolor属性，XAML解析就很好（我得到了预期的结果）。似乎在DateTemplate中包含了转换器。参考资料应该保证可以找到它，但由于某些原因，它没有被找到

我还尝试将转换器资源的声明移到树的更高位置（到窗口级别），但这也不起作用。它似乎能够找到“\u gridViewCenterItemStyle”，但由于某种原因，它拒绝找到转换器

非常感谢您的任何想法

问题解决了：我搜索了整个项目，发现在我的一个资源字典中有一个额外的BlockToBrushConverter资源声明副本，具有相同的x:Key。一旦我消除了重复，问题就消失了。

为了防止有一天其他人看到这个问题，我在这个问题顶部给出的代码实际上是有效的。错误在于我在XAML的其他地方有以下声明：

<local:BlockToBrushConverter
    x:Key="_blockToBrushConverter" />

我相信这种重复阻止了在本地为DynamicDataTemplate声明资源（它无法在同一上下文中两次创建同名资源）

---

对我来说，有一件事是无法解决的，那就是为什么一些静态资源需要在本地声明，而其他的（如_GridViewCenterItemStyleStaticResource）可以在树中更高的位置（如窗口级别）声明，而没有问题。

我生成了一个与调试打印非常类似的数据模板-当我加载它时，我得到了“在类型DataTemplate中找不到可附加的属性资源”，尽管我的命名空间包括和xaml的其余部分除了控件之外是相同的
