C# .Net核心-设置全局小数分隔符，与区域性无关

using System;

class Program
{
    static void Main()
    {
        var culture = System.Globalization.CultureInfo.InvariantCulture;
        var numberFormat = (System.Globalization.NumberFormatInfo)culture.NumberFormat.Clone();
        numberFormat.NumberDecimalSeparator = ","; // 设置小数分隔符为逗号

        System.Globalization.CultureInfo.DefaultThreadCurrentCulture = culture;
        System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = culture;
        System.Threading.Thread.CurrentThread.CurrentCulture = culture;
        System.Threading.Thread.CurrentThread.CurrentUICulture = culture;
        System.Threading.Thread.CurrentThread.CurrentCulture.NumberFormat = numberFormat;
        System.Threading.Thread.CurrentThread.CurrentUICulture.NumberFormat = numberFormat;

        // 在这之后的代码中，使用小数时将会使用逗号作为小数分隔符
    }
}
