예제

static void Main()
{
    DbConnectionStringBuilder builder1 =
        new DbConnectionStringBuilder();
    builder1.ConnectionString =
        "Value1=SomeValue;Value2=20;Value3=30;Value4=40";
    Console.WriteLine("builder1 = " + builder1.ConnectionString);

    DbConnectionStringBuilder builder2 =
        new DbConnectionStringBuilder();
    builder2.ConnectionString =
        "value2=20;value3=30;VALUE4=40;Value1=SomeValue";
    Console.WriteLine("builder2 = " + builder2.ConnectionString);

    DbConnectionStringBuilder builder3 =
        new DbConnectionStringBuilder();
    builder3.ConnectionString =
        "value2=20;value3=30;VALUE4=40;Value1=SOMEVALUE";
    Console.WriteLine("builder3 = " + builder3.ConnectionString);

    // builder1 and builder2 contain the same
    // keys and values, in different order, and the
    // keys are not consistently cased. They are equivalent.
    Console.WriteLine("builder1.EquivalentTo(builder2) = " +
        builder1.EquivalentTo(builder2).ToString());

    // builder2 and builder3 contain the same key/value pairs in the
    // the same order, but the value casing is different, so they're
    // not equivalent.
    Console.WriteLine("builder2.EquivalentTo(builder3) = " +
        builder2.EquivalentTo(builder3).ToString());

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

Sub Main()
    Dim builder1 As New DbConnectionStringBuilder
    builder1.ConnectionString = _
        "Value1=SomeValue;Value2=20;Value3=30;Value4=40"
    Console.WriteLine("builder1 = " & builder1.ConnectionString)

    Dim builder2 As New DbConnectionStringBuilder
    builder2.ConnectionString = _
        "value2=20;value3=30;VALUE4=40;Value1=SomeValue"
    Console.WriteLine("builder2 = " & builder2.ConnectionString)

    Dim builder3 As New DbConnectionStringBuilder
    builder3.ConnectionString = _
        "value2=20;value3=30;VALUE4=40;Value1=SOMEVALUE"
    Console.WriteLine("builder3 = " & builder3.ConnectionString)

    ' builder1 and builder2 contain the same
    ' keys and values, in different order, and the 
    ' keys are not consistently cased. They are equivalent.
    Console.WriteLine("builder1.EquivalentTo(builder2) = " & _
        builder1.EquivalentTo(builder2).ToString())

    ' builder2 and builder3 contain the same key/value pairs in the 
    ' the same order, but the value casing is different, so they're
    ' not equivalent.
    Console.WriteLine("builder2.EquivalentTo(builder3) = " & _
        builder2.EquivalentTo(builder3).ToString())

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

이 샘플은 다음 출력을 표시합니다.

builder1 = value1=SomeValue;value2=20;value3=30;value4=40
builder2 = value2=20;value3=30;value4=40;value1=SomeValue
builder3 = value2=20;value3=30;value4=40;value1=SOMEVALUE
builder1.EquivalentTo(builder2) = True
builder2.EquivalentTo(builder3) = False

설명

키 이름 비교는 대/소문자를 구분하지 않습니다. 값 비교는 대/소문자를 구분합니다.

이 메서드 EquivalentTo 는 true 키/값 쌍이 순서에 관계없이 같은지 반환합니다. 연결 문자열 내에서 순서가 중요하지 않으므로 두 연결 문자열의 연결 동작은 동일합니다. 그러나 순서가 다르면 이러한 연결 문자열에 따라 연결의 연결 풀링 동작에 영향을 줄 수 있습니다.
