我有一个名为c_invPrd的类，其代码如下。从C＃中的类中获取所有属性名称

public readonly string ITEM_NO          = "ITEM_NO"; 
public readonly string PRD_INDEX         = "PRD_INDEX"; 
public readonly string PRD_CD          = "PRD_CD"; 
public readonly string PRD_DESC         = "PRD_DESC"; 
public readonly string PRINCIPAL_IND        = "PRINCIPAL_IND"; 
public readonly string PROMO_IND         = "PROMO_IND"; 
public readonly string PRDCAT1_CD         = "PRDCAT1_CD"; 
public readonly string PRDCAT2_CD         = "PRDCAT2_CD"; 
public readonly string PRDCAT3_CD         = "PRDCAT3_CD"; 
public readonly string PRDCAT4_CD         = "PRDCAT4_CD"; 
public readonly string PRDCAT5_CD         = "PRDCAT5_CD"; 
public readonly string PRDCAT6_CD         = "PRDCAT6_CD"; 
public readonly string PRDCAT7_CD         = "PRDCAT7_CD"; 
public readonly string PRDCAT8_CD         = "PRDCAT8_CD"; 
public readonly string PRDCAT9_CD         = "PRDCAT9_CD"; 
public readonly string PRDCAT10_CD         = "PRDCAT10_CD"; 
private readonly Type typeof_ITEM_NO        = typeof(int); 
private readonly Type typeof_PRD_INDEX       = typeof(int); 
private readonly Type typeof_PRD_CD        = typeof(string); 
private readonly Type typeof_PRD_DESC        = typeof(string); 
private readonly Type typeof_PRINCIPAL_IND      = typeof(string); 
private readonly Type typeof_PROMO_IND       = typeof(string); 
private readonly Type typeof_PRDCAT1_CD       = typeof(string); 
private readonly Type typeof_PRDCAT2_CD       = typeof(string); 
private readonly Type typeof_PRDCAT3_CD       = typeof(string); 
private readonly Type typeof_PRDCAT4_CD       = typeof(string); 
private readonly Type typeof_PRDCAT5_CD       = typeof(string); 
private readonly Type typeof_PRDCAT6_CD       = typeof(string); 
private readonly Type typeof_PRDCAT7_CD       = typeof(string); 
private readonly Type typeof_PRDCAT8_CD       = typeof(string); 
private readonly Type typeof_PRDCAT9_CD       = typeof(string); 
private readonly Type typeof_PRDCAT10_CD       = typeof(string); 
public c_invIndPrd(DMSFW.Objects.Argument arg) 
    : base (arg) { 
} 
public c_invIndPrd() 
{ 
}

如何创建一个列表C＃把所有喜欢ITEM_NO，PRD_INDEX，PRD_CD，PRD_DESC，PRINCIPAL_IND属性等进入名单由以下访问c_invPrd类？我正在使用sharpdeveloper作为我的IDE。

回答：

这个代码看起来非常非常奇怪 - 它看起来像你想要一些私人领域，但只是string的：

var fields = typeof(c_invPrd).GetFields(
     BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public) 
    .Where(f => f.FieldType == typeof(string)).ToArray();

如果你只想名字：如果你想

var fields = typeof(c_invPrd).GetFields(
     BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public) 
    .Where(f => f.FieldType == typeof(string)).Select(f => f.Name).ToArray();

值那么你需要一个实例类型，然后使用FieldInfo.GetValue：

c_invPrd obj = ... 
var fields = typeof(c_invPrd).GetFields(
      BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public) 
    .Where(f => f.FieldType == typeof(string)) 
    .Select(f => (string)f.GetValue(obj)).ToArray();

坦率地说，这段代码只是莫名其妙。无论这些事情应该是const（为string）或static readonly（为Type） - 或者他们应该是经常性的，即

public int ITEM_NO {get;set;} // I'd use ItemNumber if it was me, but... 
public string PRD_CD {get;set;} // I'm going to guess... ProductCode?
