Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets 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; }
static member CurrentInfo : System.Globalization.NumberFormatInfo
Public Shared ReadOnly Property CurrentInfo As NumberFormatInfo
Property Value
A read-only NumberFormatInfo based on the culture of the current thread.
Examples
The following example shows that the objects returned by the CurrentInfo and CultureInfo.CurrentCulture.NumberFormat
properties are identical. 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);
}
}

Retrieving a NumberFormatInfo object from the CurrentInfo property is equivalent to retrieving a NumberFormatInfo object from the CultureInfo.CurrentCulture.NumberFormat
property.
