将XML数据发送到SQL server时替换/避免XML C#中的unicode字符

下面是创建XML数据的代码，这样我就可以将XML数据作为字符串发送到Sql server进行批量插入

---

因此，除了编码/解码的概念外，请提供关于转义这些字符或任何其他插入到数据库中的方法的建议

---

谢谢。

找到了解决方案。当我使用XML数据类型而不是varchar（max）时，它保存了详细信息。因此，问题在于参数的数据类型。我已改为nvarchar（max），它工作正常

nvarchar（马克斯）做到了这一点

Hm。由于.NET和SQL Server都应该完全启用unicode，我猜错误在代码中的某个地方。也许您没有在XML头中传递正确的编码？或者在将字符串传递到SQL server之前将其转换为ASCII或ANSI？在数据层中，我收到此错误..因此StoredProcess中一定存在一些问题。我没有在XML标头中使用任何编码。如何在上述代码中添加此编码..请让我知道
