    ConnectionString Property (ExactTargetConnection)
    In This Topic
    Gets or sets the string used to open an ExactTarget connection.
    Syntax
    'Declaration
     
    Public Shadows Property ConnectionString As String
    public new string ConnectionString {get; set;}

    Property Value

    The connection string that includes the parameters needed to establish the initial connection. The default value is an empty string ("").
    Remarks
    When ConnectionString property is assigned a value, connection closes. Many of the connection string values have corresponding properties. When the connection string is set, all of these properties are updated, except when an error is detected. In this case, none of the properties are updated. ExactTargetConnection properties return only those settings contained in the ConnectionString.

    Resetting the ConnectionString on a closed connection resets all connection string values (and related properties).

    The connection string is parsed immediately after being set. If errors in syntax are found when parsing, a runtime exception, such as System.ArgumentException, is generated. Other errors can be found only when an attempt is made to Open the connection.

    The ConnectionString is similar to an OLE DB connection string. Values may be delimited by single or double quotes, (for example, name='value' or name="value"). Either single or double quotes may be used within a connection string by using the other delimiter, for example, name="value's" or name= 'value"s', but not name= 'value's' or name= ""value"". All blank characters, except those placed within a value or within quotes, are ignored. Keyword value pairs must be separated by a semicolon (;). If a semicolon is part of a value, it also must be delimited by quotes. No escape sequences are supported. The value type is irrelevant. Names are not case sensitive. Arguments names may occur only once in the connection string.

    The following table lists the valid names for values within the ConnectionString.

    Name Description
    App Client Id The client ID from the Salesforce Marketing Cloud App Center.
    App Client Secret The client Secret from the Salesforce Marketing Cloud App Center.
    App Sandbox Determines whether to use a sandbox account for App Center Client authentication.
    Authentication Type Determines the authentication method to use. The following kinds are supported: AppCenterClient (deprecated), RefreshToken, ServerToServer, and UsernamePassword. See AuthenticationType for more information.
    ClientIDs The comma separated list of partner account ids and business units (used for the SELECT queries only).
    Connection Lifetime When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by Connection Lifetime. The default value is 0 (connection always returns to pool).
    Connect Timeout -or- Connection Timeout The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. The default value is 15.
    Default Command Timeout The time in seconds to wait while trying to execute a command before terminating the attempt and generating an error. A value of 0 indicates no limit.
    Initialization Command Specifies a data source-specific command that should be executed immediately after establishing the connection.
    Max Pool Size The maximum number of connections allowed in the pool. Setting the Max Pool Size value of the ConnectionString can affect performance. The default value is 100.
    Min Pool Size The minimum number of connections allowed in the pool. The default value is 0.
    Password The password for UserNamePassword authentication.
    Persist Security Info Indicates if security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state.
    Pooling If true, by default, the ExactTargetConnection object is drawn from the appropriate pool or is created and added to the appropriate pool.
    Proxy Host The host name or IP address of proxy server.
    Proxy Password The password for the proxy server account.
    Proxy Port The port number of the proxy server. The default value is 3128.
    Proxy User The proxy server account name.
    Run Once Command A command to execute when the connection is opened the first time and not executed when the connection is taken from the pool.
    Readonly Determines whether the connection is read-only (allows only SELECT statements).
    Subdomain A tenant-specific subdomain of Marketing Cloud API endpoints. It is a 28-character string starting with the letters "mc", for example, mc563885gzs27c5t9-63k636ttgm. You can find your subdomain in the url in your browser after logging in to Salesforce Marketing Cloud.
    Support Extension Objects Determines whether to allow access to ExactTarget data extensions via the connection. By default, true, which means that access is allowed. If you don't need access to ExactTarget data extensions, you may set it to false to improve connection performance.
    Url The URL of an ExactTarget instance for API UserNamePassword authentication.
    User The API User name to login using UserNamePassword authentication.
    UTC Dates Indicates whether all the datetime values retrieved from the data source are returned as UTC values or converted to local time, and whether date values, specified on the application side (for example, in SQL statements) are considered UTC or local. Default value is false.
    Example
    The following example creates a ExactTargetConnection and sets some of its properties in the connection string.
    public void CreateExactTargetConnection()
    {
      string myConnString1 = 
         "user=MyCompanyAdmin;password=mypassword;url=https://webservice.s7.exacttarget.com/Service.asmx;";
      ExactTargetConnection exactTargetConnection1 = new ExactTargetConnection(myConnString1);
      exactTargetConnection1.Open();
    }
    Public Sub CreateExactTargetConnection()
      Dim myConnString1 As String = _
          "user=MyCompanyAdmin;password=mypassword;url=https://webservice.s7.exacttarget.com/Service.asmx;"
      Dim exactTargetConnection1 As New ExactTargetConnection(myConnString1)
      exactTargetConnection1.Open()
    End Sub
