ASP.NET Core 3.0 BinderFloatingDecimalModel

Model Binder in ASP.NET Core 3.0 for Floating Point Numeric Values [double, float или decimal]

Use in your project:

using AspDotNetCore2BinderFloatingDecimalModel;
// ...
public class Startup
{
	// ...
	public void ConfigureServices(IServiceCollection services)
	{
		// ...
		services.AddMvc(opts =>
		{
			opts.ModelBinderProviders.Insert(0, new CustomDecimalModelBinderProvider());
		}).SetCompatibilityVersion(CompatibilityVersion.Version_3_0);
	}
}

A well-known feature of the standard model binding in ASP.NET Core 3.0 is that it is impossible to fully use floating point value types in properties. The built-in model binding tries to process all numeric values ​​as integers, even if the type of the model property is declared as a floating-point number. From here it becomes problematic to use models with properties of types [double, float or decimal] in forms.

This model binding not only fixes this problem, but also frees the user from restricting the use of a fractional separator (period or comma). This binder allows you to use any fraction separator. Any separator is forcibly replaced with a system one before conversion.

Regex FloatSeparator = new Regex(@"[.,]", RegexOptions.Compiled);
////////////////////////////////////////////////////
// replace the fractional separator with the current system
FieldValueAsNormalString = FloatSeparator.Replace(FieldValueAsNormalString, CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator);

In addition, a truncated format for recording numbers is allowed. For example: 0.5 and .5 will give one result. As well as 5.0 == 5. This feature looks ambiguous and controversial ⇒ you can comment out this "value processing".

if (FloatSeparator.IsMatch(FieldValueAsString))
	FieldValueAsNormalString = "0" + FieldValueAsNormalString + "0";

Special attention is required to the regular expression pattern of the intended value. File: ** CustomFloatingModelBinder.cs **

protected readonly Regex FloatPattern = new Regex(@"^(-?)[0-9]*(?:[.,][0-9]*)?$", RegexOptions.Compiled);
