"；int”；至“；通用的“；数据类型在c#中给出错误

我是c#初学者，创建了适用于"int"类型符号的huffman tree，但下一步是使其成为generic。在解释中，symbol应该适用于每个data type我的意思是，每个数据类型的符号都可以是int、ulong、short等类型。实际上，我正在读取一个binary file，并试图找到每个符号重复的频率(符号重复的次数就是它的频率(，所以我的节点中的这个符号应该在32/64位体系结构上适用于"short"、"long"answers"unsigned"。目前，我在代码中使用了"int"，但它可能是"short"或任何其他的

我已经尝试过了，但我有错误，下面给出了我的代码，它包含有错误的行号。错误是：获得的误差为：

有人能帮我删除这些错误吗？让这个"符号"适用于所有数据类型，如"短"、"长"等。
