NumberFormatInfo.CurrentInfo 屬性

定義

命名空間:

System.Globalization

組件:

System.Runtime.dll

來源:

NumberFormatInfo.cs

取得根據目前文化特性格式化值的唯讀 NumberFormatInfo。

C#

public static System.Globalization.NumberFormatInfo CurrentInfo { get; }

屬性值

NumberFormatInfo

根據目前執行緒文化特性的唯讀 NumberFormatInfo。

範例

下列範例顯示 和 CultureInfo.CurrentCulture.NumberFormat 屬性所CurrentInfo傳回的物件完全相同。 然後，它會使用反映，在目前文化特性為 en-US 的系統上顯示 屬性所CurrentInfo傳回物件的屬性值NumberFormatInfo。

C#

using System;
using System.Collections;
using System.Globalization;
using System.Reflection;

public class Example : IComparer
{
   public static void Main()
   {
      NumberFormatInfo nfi1 = NumberFormatInfo.CurrentInfo;
      NumberFormatInfo nfi2 = CultureInfo.CurrentCulture.NumberFormat;
      Console.WriteLine("Objects equal: {0}", nfi1.Equals(nfi2));
      Console.WriteLine("Equal references: {0}\n", Object.ReferenceEquals(nfi1, nfi2));

      PropertyInfo[] props = nfi1.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public);
      Array.Sort(props, new Example());
      Console.WriteLine("Properties of NumberFormat.CurrentInfo object:");
      foreach (var prop in props) {
         if (prop.PropertyType.IsArray) {
            Array arr = prop.GetValue(nfi1) as Array;
            Console.Write(String.Format("   {0}: ", prop.Name) + "{ ");
            int ctr = 0;
            foreach (var item in arr) {
               Console.Write("{0}{1}", item, ctr == arr.Length - 1 ?" }" : ", ");
               ctr++;
            }
            Console.WriteLine();
         }
         else {
            Console.WriteLine("   {0}: {1}", prop.Name, prop.GetValue(nfi1));
        }
      }
   }

   public int Compare(Object x, Object y)
   {
      if (x == null && y == null) return 0;

      PropertyInfo px = x as PropertyInfo;
      if (px == null) return -1;

      PropertyInfo py = y as PropertyInfo;
      if (py == null) return 1;

      return String.Compare(px.Name, py.Name);
   }
}

備註

從屬性擷NumberFormatInfoCurrentInfo取 物件相當於從 CultureInfo.CurrentCulture.NumberFormat 屬性擷取 NumberFormatInfo 物件。
