I am trying to开发者_开发知识库 make this work but have been unlucky it is giving me th following error

Error in Like operator: the string pattern '%testing : | / - “ ‘ & * # @%' is invalid.

This search works as long as it doesnt contain a string as the one above.. This is my code for the search

DataRow[] rows = GetAllItems.Select("Name like '%" + cleanedText + "%'");

I tried - Modified per cHaos (still errors though)

  string cleanedText =  SearchText.Replace("\"", "\\\"").Replace("'", "''");

but no luck when i enter the following string in the search although i know it is in the data

testing : | / - “ ‘ & * # @%

Anyone has a nice suggestion

Thank you


Both % and * can be used interchangeably for wildcard characters in the LIKE comparison.

As such you will need to enclose these characters in square brackets in your expression string like so:

Name like '%testing : | / - “ ‘ & [*] # @%'

See DataColumn.Expression.

From the above link:

Wildcard Characters

Both the * and % can be used interchangeably for wildcard characters in a LIKE comparison. If the string in a LIKE clause contains a * or %, those characters should be enclosed in brackets ([]). If a bracket is in the clause, each bracket character should be enclosed in brackets (for example [[] or []]).
