在 C# 中获取当前类型的特定字段，代码如下 −

示例

using System;
using System.Reflection;
public class Demo {
   public static void Main() {
   Type type = typeof(Subject);
      try {
         FieldInfo fieldInfo = type.GetField("SubName");
         Console.WriteLine("FieldInfo = {0}", fieldInfo);
      }
      catch (ArgumentNullException e) {
         Console.Write("{0}", e.GetType(), e.Message);
      }
   }
}
public class Subject {
   public string SubName = "Science";
}

输出

这将产生以下输出 −

FieldInfo = System.String SubName

示例

让我们看另一个例子 −

using System;
using System.Reflection;
public class Demo {
   public static void Main() {
      Type type = typeof(Subject);
      try {
         FieldInfo fieldInfo = type.GetField(null);
         Console.WriteLine("FieldInfo = {0}", fieldInfo);
      }
      catch (ArgumentNullException e) {
         Console.Write("{0}", e.GetType(), e.Message);
      }
   }
}
public class Subject {
   public string SubName = "Science";
}
