能告诉我如何读取在一个类中声明的枚举的值吗? [英] Could any tell me how to read the values of the enums declared in a class?

问题描述

大家好！

我正在使用C#中的system.reflection.我必须使用反射来读取枚举值.但是这样做并没有获得值.

有什么可以帮助我完成该过程的吗?

Hi everyone!

I am working on system.reflection in C#. I have to read the enums values using reflection.But while doing am not getting the values.

Can any help me how to do the process?

private void ExtractSampleConstants(Type t)
    {
        FieldInfo[] FInfo = t.GetFields(BindingFlags.DeclaredOnly | BindingFlags.IgnoreCase | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Static);
        foreach (FieldInfo fin in FInfo)
        {
            string ReplaceStr=string.Empty;
            string Fname = fin.Name;
            object Fvalue = fin.GetValue(fin.Name);
            if(t.Name=="SampleConstants")
                ReplaceStr=fin.DeclaringType.Name.ToString()+"."+Fname;
            else
                ReplaceStr = ConvertToShortForm(fin.DeclaringType.FullName.ToString()) + "." + Fname;
            DataDecl.FINFO.Add(new ConstInfo(Fname, Fvalue, ReplaceStr));
        }

推荐答案

如果必须为此使用反射，则替换行

If you must use reflection for this, then replace your line

object Fvalue = fin.GetValue(fin.Name);

with

with

object Fvalue = fin.GetRawConstantValue();

您的意思是序数值?

您所需要做的就是将其强制转换为适当的整数类型.

You you mean the ordinal values?

All you have to do is cast it to the appropriate integer type.

您可以使用Enum类的静态方法:

You could use the static methods of the Enum class:

public enum SomeEnum
{
  SomeItem,
  SomeItem2,
  SomeItem3
}

public void Something()
{
  var values = Enum.GetValues(typeof(SomeEnum));
}

而且您不必费解反射.

and you''ll not have to mess around with reflection.
