Razor-如何获取字符串的n个数字字符？

Question

I have an asp.net mvc 4 application with the following

Model

public string Price {get;set;}

it saves in database a string, eg. "41.99".

View

@foreach(var item in Model)
{
   <div class="price">@item.Price</div>
}

it returns the value "41.99" all good here.

however I would like to pick the values differently.

Below is the Html output for what I need

@foreach(var item in Model)
{
    <div class="price">
    <span class="dollar">41</span>
    <span class="cents">99</span>
</div>
}

• Please Note that the value is split in 2 parts and the dot is left out.
• The string will be inserted on input field as money, so it need to be inserted as "41.99"
• Other consideration is if the value before the dot are 1, 11, 111, 1111 characters, it need display all numbers.

So how could I archive this?

@foreach(var item in Model)
{
 <div class="price">
     <span class="dollar">@item.Price(first part)</span>
     <span class="cents">@item.Price(second part)</span>
 </div>
}

Any help or guindance would be apprecciated.

Answer 1

If your data is string then

var price = "41.99";
var parts = price.Split('.');
var dollar = parts[0];
var cents = parts[1];

If your data is decimal

decimal price = 41.99m;
var dollar = (int)price;
var cents = (int)((price % 1) * 100);

Answer 2

Setting aside the fact you should not be using string to represent numerical values and use decimal instead for money values... and the fact that . is not the only separator (depending on locale)...

String.Split is the easiest way to split the string on a separator:

var parts = item.Price.Split(`.`);

Now you have parts[0] with "dollar" value, and need to deal with fractional part which may or may not be there. Note that you may need to pad cents value if you need something like 04 instead of just 4

  @{ 
     var parts = @item.Price.Split('.');
     var cents = (parts.Length == 2) ? cents = parts[1] : "0";
  }
  <span class="dollar">@parts[0]</span>
  <span class="cents">@cents</span>

Answer 3

Thanks for all replies

I figured it out combining the answers here with some suggestions.

here is the answer for my question: Model:

public double Price { get; set; }

Controller:

public ActionResult Details(int id)
{
var data = _Context.Products.Where(d => d.ProductId == id).First();

if (data == null)
{
return HttpNotFound();
}
return View(data);
}

In View:

string s = Model.Price.ToString("0.00", System.Globalization.CultureInfo.InvariantCulture);
string[] parts = s.Split('.');
int i1 = int.Parse(parts[0]);
int i2 = int.Parse(parts[1]);

<span>@i1</span>
<span class="decimal">@i2</span>

Works like a charm

Thanks a lot
