Need to modify a text field with commas.

Posted on 2011-09-05
Last Modified: 2012-05-12
I have a field "MetaKeywords" that contains values separated by commas, like:

"dome cam, dummy cam, fake Surveillance, fake security, spy, cams, cameras"

I need to do 2 things to it:

1. Remove the space after the commas, like : "dome cam,dummy cam,fake........ "

2. Limit the field to just 5 values separated by commas, like : "dome cam, dummy cam, fake Surveillance, fake security, spy"

How can this be done in C#? thanks

Try this:
string value = "dome cam, dummy cam, fake Surveillance, fake security, spy, cams, cameras";
string[] parts = value.Split(',');

for (int i = 0; i < parts.Length; i++)
    if (i < 5)
        parts[i] = parts[i].Trim();
        parts[i] = string.Empty;

string result = string.Join(",", parts).TrimEnd(',');

You could also do a extension-method-based approach:
using System.Linq;


string value = "dome cam, dummy cam, fake Surveillance, fake security, spy, cams, cameras";

string result = value.Split(',')
                     .Aggregate((accum, curr) => accum += curr.Trim() + ",").TrimEnd(',')
