I am trying to write a Regex pattern to modify the caption of my datagridview. I need to remove following characters from each string: space [ ] * # ? / \\ @ ( ) . "" '' I am super confused and I need your help in defining the patter of the Regex in C#. This is my sample code:
DataTable d_new = d;
for (int i = 0; i < d.Columns.Count; i++)
{
string t = d.Columns[i].Caption;
string regex = "\\s+"; // this needs to Be expanded
string t_new = Regex.Replace(t, regex, "_");
d.Columns[i].Caption = t_new;
}
var invalidChars = new HashSet<char>(@"[]*#?/\@()");
var output = new string( input.Where(c => !invalidChars.Contains(c)).ToArray() );
This would match what you want, just replace with an empty string or what you want.
[ \[\]*#?/\\@()."']
But in this case an regex is a bit overkill, you could just use Remove
.
这应该可以解决问题:
string regex = "[\[\]*#?\/\\@()."']";
