                问题描述

                限时送ChatGPT账号..

                我是 Winforms 开发的新手,我将在文本框中向我的用户显示数据.文本框将与货币数据绑定,因此我尝试格式化正在显示的值.

                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.

                我查看了一个蒙面文本框,但这并不是我想要的,因为它没有将美分放在小数点后.

                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.

                我需要为每个与此类似的文本框编码吗?

                Do I need to code for each textbox similar to this?

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

                我有很多需要格式化的文本框,所以我想知道是否需要为每个文本框都这样做.有人有什么建议吗?

                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?

                推荐答案

                您可以创建自己的 TextBox 派生自标准文本框

                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);
                        }
                    }
                }
                

                用法:

                   textbox.Format = "c";
                   textbox.Datasource = DataSet.DataView[0].Amount;
