i’m stuck and cannot find easy way to solve this issue, let’s suppose i have below model:

public classs FooModel
{
  string name{get;set;}
  double doubleFoo{get;set}
}

i have built a class, usable from a HTMLform, where user can upload an excel file and fill above value (with OpenXML). Let’s say this class return a “FooObject”, with properties from FooModel.

FooModel FooObject = new FooModel()
{
 name = nameFromFooObject,
 doubleFoo = doubleFooFromObject, /* <= this variable contains well dot decimal separation, and look like "0.061065380952380954" */
}

I have checked, doubleFoo that i get from excel file is dot separated value.

Now, my controller return a view, where a form is populated with value sent from Excel file.

<form asp-action="FooAdd">

<div>
<label asp-for="name" class="control-label"></label>
<input asp-for="name" class="form-control"/>
<span asp-validation-for="name" class="text-danger"></span>
</div>

<div>
<label asp-for="doubleFoo " class="control-label"></label>
<input asp-for="doubleFoo " class="form-control"/>
<span asp-validation-for="doubleFoo " class="text-danger"></span>
</div>

</form>

form once populated with object sent from excel

here come the trouble, doubleFoo is now showed on my form with comma separation like “0,061065380952380954”, and i can’t send the form to add object to database.

Why ? How can i easily solve this ?

tried several from stackoverflow without success
