十进制类型在 .ASP.net Core Razor 绑定中丢失精度

Question

We have been facing issue where .net core rounding decimal values to 2 decimal places we want more precision of upto 5 decimal places. Issue already discussed this question. The solution provided doesn't seem to be very elegant. Is there aa way to override this default behavior

Answer 1

1) Use decimal(18, 5) in SQL Server table

2) Add step="0.00001" in your html input or whatever

<input type="number" asp-for="Amount" step="0.00001" />

Result

This is still old. It has been around since old .net framework. Don't understand why you find it so hard to solve. oo

Answer 2

您可以将 asp-format 用于输入标签，如下所示：

 <input asp-for='data' asp-format="{0:0.00000}" class="form-control" />

Answer 3

Another option is to write your own tag helper that format the number with 5 decimal places. And it can apply through out the application. This way, you have more control on how/where you display the numbers. And all formatting code/logic is put in 1 place, so easier for you to change in future.
