WinForms格式文本框到货币 [英] Winforms Format TextBox To Currency

问题描述

我是Winforms开发的新手，我将在文本框中向用户显示数据。该文本框将数据绑定与货币数据，所以我想格式化正在显示的值。

我看了一个Masked Text Box，但是这不是我正在寻找的，因为它不会把小数点后面的分。 b
$ b

我是否需要为每个文本框编写相似的代码？

  TextBox.Text = DataSet.DataView [0] .Amount.ToString（ C）; 
  

我有很多的文本框需要格式化，所以我想知道如果我需要这样做每一个。有没有人有任何建议？

解决方案

您可以创建自己的文本框从标准的一个派生

  public class TextBoxEx：TextBox 
 {
 public string Format {get;组; } 
 
 private object datasource = new object（）; 
公共对象数据源
 {
 get {return datasource; } 
 set 
 {
 datasource = value; 
 if（datasource == null）
 base.Text = string.Empty; 
 else if（string.IsNullOrWhiteSpace（Format））
 base.Text = datasource.ToString（）; 
 else 
 base.Text = string.Format（{0：+ Format +}，datasource）; 
 
 
 
 
 
 $ b用法：
  textbox.Format =c; 
 textbox.Datasource = DataSet.DataView [0] .Amount; 
  
 
I am new to Winforms development and I going to be displaying data to my users in a textbox.  The textbox will be databound with data that is currency so I am trying to Format the value that is being displayed.  

I looked at a Masked Text Box but that isn't exactly what I am looking for because it doesn't put the cents after the decimal.

Do I need to code for each textbox similar to this?
TextBox.Text = DataSet.DataView[0].Amount.ToString("c");
I have alot of textboxes that need to be formatted so I am wondering if I need to do this for each one.  Does anyone have any suggestions?
解决方案
You can create your own TextBox derived from standard one
 public class TextBoxEx : TextBox
{
    public string Format { get; set; }

    private object datasource = new object();
    public object Datasource
    {
        get { return datasource; }
        set 
        {
            datasource = value;
            if (datasource == null)
                base.Text = string.Empty;
            else if(string.IsNullOrWhiteSpace(Format))
                base.Text = datasource.ToString();
            else
                base.Text = string.Format("{0:"+ Format + "}",datasource);
        }
    }
}
Usage: 
   textbox.Format = "c";
   textbox.Datasource = DataSet.DataView[0].Amount;
