BTW: It is a very bad idea to do SQL queries (which I assume you are) using direct text - Google for SQL Injection Attack for details. Use a Parameterized Query instead - look at SqlCommand.AddWithValue for details. [Edit]Corrected spelling of Query[/edit]

Solution 1

Your method definition is:

public DataSet SearchItem(string title, string flag)

I.e. it requires two parameters, both string.
When you try to call it, the error message means you are using:

DataSet ds = SearchItem();

I.e. you have not provided either parameter.

Solution 2

You are invoking it as SearchItem(), it should be SearchItem("xxx", "true")

Solution 3

A couple of things. As Griff said, this code is ripe for people to attack your database, it's a mess. The second thing is, if you could not understand the meaning of the error message you got, you should focus on learning basic C# before you consider also learning SQL.
