SqlConnectionStringBuilder.InitialCatalog プロパティ

定義

接続に関連付けられたデータベースの名前を取得または設定します。

public:
 property System::String ^ InitialCatalog { System::String ^ get(); void set(System::String ^ value); };
public string InitialCatalog { get; set; }
[System.ComponentModel.TypeConverter(typeof(System.Data.SqlClient.SqlConnectionStringBuilder+SqlInitialCatalogConverter))]
public string InitialCatalog { get; set; }
member this.InitialCatalog : string with get, set
[<System.ComponentModel.TypeConverter(typeof(System.Data.SqlClient.SqlConnectionStringBuilder+SqlInitialCatalogConverter))>]
member this.InitialCatalog : string with get, set
Public Property InitialCatalog As String

プロパティ値

InitialCatalog プロパティの値。値が指定されていない場合は String.Empty

属性

例外

値を null に設定するには、Value を使用します。

次の例では、単純な接続文字列を作成し、SqlConnectionStringBuilder クラスを使用して、データベースの名前をこの接続文字列に追加します。 このコードでは、クラスがシノニム ("Database") を適切なプロパティ値に変換できたかどうかを確認するために、InitialCatalog プロパティの内容を表示します。

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        try
        {
            string connectString = "Data Source=(local);" +
                "Integrated Security=true";

            SqlConnectionStringBuilder builder =
                new SqlConnectionStringBuilder(connectString);
            Console.WriteLine("Original: " + builder.ConnectionString);

            // Normally, you could simply set the InitialCatalog
            // property of the SqlConnectionStringBuilder object. This
            // example uses the default Item property (the C# indexer)
            // and the "Database" string, simply to demonstrate that
            // setting the value in this way results in the same
            // connection string:
            builder["Database"] = "AdventureWorks";
            Console.WriteLine("builder.InitialCatalog = "
                + builder.InitialCatalog);
            Console.WriteLine("Modified: " + builder.ConnectionString);

            using (SqlConnection connection =
                new SqlConnection(builder.ConnectionString))
            {
                connection.Open();
                // Now use the open connection.
                Console.WriteLine("Database = " + connection.Database);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

        Console.WriteLine("Press any key to finish.");
        Console.ReadLine();
    }
}
Imports System.Data.SqlClient
    
Module Module1
    Sub Main()
        Try
            Dim connectString As String = _

            Dim builder As New SqlConnectionStringBuilder(connectString)
            Console.WriteLine("Original: " & builder.ConnectionString)

            ' connection string.
            builder("Database") = "AdventureWorks"
            Console.WriteLine("builder.InitialCatalog = " _
                & builder.InitialCatalog)
            Console.WriteLine("Modified: " & builder.ConnectionString)

            Using connection As New SqlConnection(builder.ConnectionString)
                connection.Open()
                ' Now use the open connection.
                Console.WriteLine("Database = " & connection.Database)
            End Using

        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try

        Console.WriteLine("Press any key to finish.")
        Console.ReadLine()
    End Sub
