Set this in your web.config

 &lt;globalization uiCulture="en" culture="en-US" /&gt;

You appear to be using a server that is setup with a language that uses comma's instead of decimal places. You can adjust the culture to one that uses the comma's in a way that your application is designed, such as en-US.

I have just revisited the issue in a real project and finally found a working solution. Proper solution is to have a custom model binder for the type <code>decimal</code> (and <code>decimal?</code> if you're using them):

<pre><code>using System.Globalization;
using System.Web.Mvc;

public class DecimalModelBinder : DefaultModelBinder
{
 public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
 {
 object result = null;

 // Don't do this here!
 // It might do bindingContext.ModelState.AddModelError
 // and there is no RemoveModelError!
 // 
 // result = base.BindModel(controllerContext, bindingContext);

 string modelName = bindingContext.ModelName;
 string attemptedValue = bindingContext.ValueProvider.GetValue(modelName)?.AttemptedValue;

 // in decimal? binding attemptedValue can be Null
 if (attemptedValue != null)
 {
 // Depending on CultureInfo, the NumberDecimalSeparator can be "," or "."
 // Both "." and "," should be accepted, but aren't.
 string wantedSeperator = NumberFormatInfo.CurrentInfo.NumberDecimalSeparator;
 string alternateSeperator = (wantedSeperator == "," ? "." : ",");

 if (attemptedValue.IndexOf(wantedSeperator, StringComparison.Ordinal) == -1
 &amp;&amp; attemptedValue.IndexOf(alternateSeperator, StringComparison.Ordinal) != -1)
 {
 attemptedValue = attemptedValue.Replace(alternateSeperator, wantedSeperator);
 }

 try
 {
 if (bindingContext.ModelMetadata.IsNullableValueType &amp;&amp; string.IsNullOrWhiteSpace(attemptedValue))
 {
 return null;
 }

 result = decimal.Parse(attemptedValue, NumberStyles.Any);
 }
 catch (FormatException e)
 {
 bindingContext.ModelState.AddModelError(modelName, e);
 }
 }

 return result;
 }
}
</code></pre>

Then in Global.asax.cs in Application_Start():

<pre><code>ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder());
ModelBinders.Binders.Add(typeof(decimal?), new DecimalModelBinder());
</code></pre>

Note that code is not mine, I actually found it at Kristof Neirynck's blog <a href="http://www.crydust.be/blog/2009/07/30/custom-model-binder-to-avoid-decimal-separator-problems/" rel="noreferrer">here</a>. I just edited a few lines and am adding the binder for a specific data type, not replacing the default binder.

I'm working with the <a href="http://www.codeplex.com/nerddinner" rel="noreferrer">NerdDinner</a> application trying to teach myself ASP.NET MVC. However, I have stumbled upon a problem with globalization, where my server presents floating point numbers with a comma as the decimal separator, but Virtual Earth map requires them with dots, which causes some problems.

I have already solved <a href="https://stackoverflow.com/questions/760258/how-to-globalize-asp-net-mvc-views-decimal-separators-in-particular">the issue with the mapping JavaScript in my views</a>, but if I now try to post an edited dinner entry with dots as decimal separators the controller fails (throwing <code>InvalidOperationException</code>) when updating the model (in the <code>UpdateModel()</code> metod). I feel like I must set the proper culture somewhere in the controller as well, I tried it in <code>OnActionExecuting()</code> but that didn't help.

How to set decimal separators in ASP.NET MVC controllers?

服务器

我正在使用应用程序，试图自学ASP.NET MVC。然而，我偶然发现了全球化的一个问题，我的服务器用逗号作为小数点分隔符显示浮点数，但Virtual Earth地图需要它们带点，这会导致一些问题。我已经解决了，但如果我现在尝试发布一个编辑过的晚餐条目，并将点作为小数点分隔符，则当更新模型(在UpdateModel()方...
