如何从字符串中删除逗号分隔的值? [英] How to remove comma separated value from a string?

问题描述

我想从字符串中删除逗号分隔的值.

I want to remove a comma separated value from the string..

假设我有一个像这样的字符串

suppose I have a string like this

string x="r, v, l, m"

我想从上述字符串中删除r，并像这样修改字符串

and i want to remove r from the above string, and reform the string like this

string x="v, l, m"

从上面的字符串中，我想删除逻辑抛出的任何值并重新格式化该字符串.它应该删除该值和旁边的逗号并重新设置字符串...

from the above string i want to remove any value that my logic throw and reform the string. it should remove the value and comma next to it and reform the string...

以下内容专门针对我的代码.我想删除从逻辑中获得的任何值，我想删除它并在其旁边添加逗号，并在删除的项目上重新设置字符串而没有空白.

The below is specific to my code.. I want to remove any value that I get from the logic, I want to remove it and comma next to it and reform the string with no empty space on the deleted item.. How can I achieve this?

offIdColl = my_Order.CustomOfferAppliedonOrder.TrimEnd(',');
if (offIdColl.Split(',').Contains(OfferID.ToString()))
{
    // here i want to perform that operation.   

}

Tombala，我像这样应用它，但是它不起作用..它返回true

}

Tombala, i applied it like this but it doesn't work..it returns true

 if (!string.IsNullOrEmpty(my_Order.CustomOfferAppliedonOrder))
                                {
                                    offIdColl = my_Order.CustomOfferAppliedonOrder.TrimEnd(',');
                                    if (offIdColl.Split(',').Contains(OfferID.ToString()))
                                    {
                                        string x = string.Join(",", offIdColl.Split(new char[] { ',' },
    StringSplitOptions.RemoveEmptyEntries).ToList().Remove(OfferID.ToString()));
                                    }
                                }
                            }

推荐答案

只需执行以下操作:

List<String> Items = x.Split(",").Select(i => i.Trim()).Where(i => i != string.Empty).ToList(); //Split them all and remove spaces
Items.Remove("v"); //or whichever you want
string NewX = String.Join(", ", Items.ToArray());
