매개 변수

반품

키가 연결 문자열 내에 있고 제거되었으면 true, 키가 없으면 false.

예외

예제

다음 예제에서는 인스턴스를 OdbcConnectionStringBuilder 만들고 메서드의 동작을 Remove 보여 줍니다.

using System.Data.Odbc;

class Program
{
    static void Main()
    {
        OdbcConnectionStringBuilder builder =
            new OdbcConnectionStringBuilder();
        builder.ConnectionString =
            "Driver={SQL Server};Server=(local);" +
            "Database=AdventureWorks;Trusted_Connection=yes;";

        Console.WriteLine(builder.ConnectionString);

        // Try to remove an existing item.
        TryRemove(builder, "Server");

        // Try to remove a nonexistent item.
        TryRemove(builder, "User ID");

        // Try to remove an existing item,
        // demonstrating that the search is not
        // case sensitive.
        TryRemove(builder, "DATABASE");

        Console.WriteLine("Press Enter to continue.");
        Console.ReadLine();
    }

    static void TryRemove(OdbcConnectionStringBuilder builder,
        string itemToRemove)
    {

        if (builder.Remove(itemToRemove))
        {
            Console.WriteLine("Removed '{0}'", itemToRemove);
        }
        else
        {
            Console.WriteLine("Unable to remove '{0}'", itemToRemove);
        }
        Console.WriteLine(builder.ConnectionString);
    }
}

Imports System.Data.Odbc  
  
Module Module1
  Sub Main()
    Dim builder As New OdbcConnectionStringBuilder
    builder.ConnectionString = _
     "Driver={SQL Server};Server=(local);" & _
     "Database=AdventureWorks;Trusted_Connection=yes;"

    Console.WriteLine(builder.ConnectionString)

    ' Try to remove an existing item.
    TryRemove(builder, "Server")

    ' Try to remove a nonexistent item.
    TryRemove(builder, "User ID")

    ' Try to remove an existing item, 
    ' demonstrating that the search is not 
    ' case sensitive.
    TryRemove(builder, "DATABASE")

    Console.WriteLine("Press Enter to continue.")
    Console.ReadLine()
  End Sub

  Sub TryRemove(ByVal builder As OdbcConnectionStringBuilder, _
      ByVal itemToRemove As String)

    If builder.Remove(itemToRemove) Then
      Console.WriteLine("Removed '{0}'", itemToRemove)
    Else
      Console.WriteLine("Unable to remove '{0}'", itemToRemove)
    End If
    Console.WriteLine(builder.ConnectionString)
  End Sub
End Module

설명

메서드는 Remove 성공을 나타내는 값을 반환하므로 인스턴스에서 OdbcConnectionStringBuilder 키/값 쌍을 제거하기 전에 키가 있는지 찾을 필요가 없습니다.
