ASP.NETCore model 中的十进制字段格式

Question

In SQL Server I have a primary key of a Table declared as follow:

[CustomerID] [numeric](18, 0) IDENTITY(1000000,1) NOT NULL,

In ASP.NET Core 2.2 model i mapped this field ad follow:

public decimal CustomerId { get; set; }

How can I make the decimal digits not appear in the application?

Answer 1

Use DisplayFormat attribute:

[DisplayFormat(DataFormatString = "{0:0}", ApplyFormatInEditMode =true)]
public decimal CustomerId { get; set; }

Answer 2

If you only need to display it without decimal places, then the formatting can be applied with a ToString anywhere, preferably where you are trying to display it. The code below will apply rounding.

CustomerId.ToString("0");

If you need to use it in some other capacity without the decimal points then you should map your model representing the database table to another model specific to what you are trying to do and supply the correct type in that model. Probably an int or string in this case.
