如何使用反射獲取類的所有靜態屬性及其值

Question

我有一個這樣的課：

public class tbl050701_1391_Fields
{
    public static readonly string StateName = "State Name";
    public static readonly string StateCode = "State Code";
    public static readonly string AreaName = "Area Name";
    public static readonly string AreaCode = "Area Code";
    public static readonly string Dore = "Period";
    public static readonly string Year = "Year";
}

我想寫一些語句，返回一個包含以下值的Dictionary<string, string> ：

Key                            Value
--------------------------------------------
"StateName"                    "State Name"
"StateCode"                    "State Code"
"AreaName"                     "Area Name"
"Dore"                         "Period"
"Year"                         "Year"

我有這個代碼來獲取一個屬性值：

public static string GetValueUsingReflection(object obj, string propertyName)
{
    var field = obj.GetType().GetField(propertyName, BindingFlags.Public | BindingFlags.Static);
    var fieldValue = field != null ? (string)field.GetValue(null) : string.Empty;
    return fieldValue;
}

我如何獲得所有房產及其價值？

我如何獲得所有屬性及其價值？

首先，您需要區分字段和屬性 。 看起來你在這里有田地。 所以你想要的東西是這樣的：

public static Dictionary<string, string> GetFieldValues(object obj)
{
    return obj.GetType()
              .GetFields(BindingFlags.Public | BindingFlags.Static)
              .Where(f => f.FieldType == typeof(string))
              .ToDictionary(f => f.Name,
                            f => (string) f.GetValue(null));
}
