NumberFormatInfo.CurrentInfo 属性

定义

获取基于当前区域性对值进行格式设置的只读的 NumberFormatInfoGets a read-only NumberFormatInfo that formats values based on the current culture.

public:
 static property System::Globalization::NumberFormatInfo ^ CurrentInfo { System::Globalization::NumberFormatInfo ^ get(); };
public static System.Globalization.NumberFormatInfo CurrentInfo { get; }
member this.CurrentInfo : System.Globalization.NumberFormatInfo
Public Shared ReadOnly Property CurrentInfo As NumberFormatInfo

属性值

NumberFormatInfo

基于当前线程的区域性的只读的 NumberFormatInfoA read-only NumberFormatInfo based on the culture of the current thread.

示例

下面的示例演示和属性返回的对象 CurrentInfo CultureInfo.CurrentCulture.NumberFormat 是相同的。The following example shows that the objects returned by the CurrentInfo and CultureInfo.CurrentCulture.NumberFormat properties are identical. 然后,它使用反射来显示 NumberFormatInfo CurrentInfo 当前区域性为 en-us 的系统上的属性所返回的对象的属性值。It then uses reflection to display the property values of the NumberFormatInfo object returned by the CurrentInfo property on a system whose current culture is en-US.

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);
   }

注解

NumberFormatInfo从属性中检索对象 CurrentInfo 等效于 NumberFormatInfo 从属性中检索对象 CultureInfo.CurrentCulture.NumberFormatRetrieving a NumberFormatInfo object from the CurrentInfo property is equivalent to retrieving a NumberFormatInfo object from the CultureInfo.CurrentCulture.NumberFormat property.
