enum TypeName
{
SystemString,
SystemInt16,
SystemInt32
}
现在有string typeName 里面存放 TypeName的枚举值,比如“SystemString”
现在要取出TypeName.SystemString:
使用Enum类的反射:
(TypeName)typevalue = (TypeName)Enum.Parse(typeof(TypeName), typeName, true);
为了事先验证typename是否是TypeName的值,代码优化为:
if (Enum.IsDefined(typeof(TypeName), typeName))
typeValue = (TypeName)Enum.Parse(typeof(TypeName), typeName, true);
else
throw new Exception("the return type does not defined");
