通用类型的 FXCop 违规

Question

在方法声明中使用 IList<Dictionary<string, string>> 作为参数类型时发生 FXCop 违规

It doesnt nest generic type IList<Dictionary<string, string>>

我该如何解决这个问题？

Answer 1

原因是：

A nested type argument is a type argument that is also a generic type. To call a member whose signature contains a nested type argument, the user must instantiate one generic type and pass this type to the constructor of a second generic type. The required procedure and syntax are complex and should be avoided.

它可以帮助您设计更简单的界面。您有 3 个案例：

• 使用SuppressMessage属性
• remove the rule from ruleset
• try to fix violations change the design to remove the nested type argument

你可以试试：

public void Method(Dictionary<string, string> param)

并使用：

var list = new IList<Dictionary<string, string>>();
list.Add(new Dictionary<string, string>{{"key1", "value1"}, {"key2", "value2"}});
list.Add(new Dictionary<string, string>{{"key11", "value11"}, {"key22", "value22"}});

foreach(var element in list)
{
    Method(element);
}
