Configurations.Contains Method
Returns a Boolean that indicates whether the items in the collection can be accessed by an index without throwing an exception.
Namespace: Microsoft.SqlServer.Dts.Runtime
Assembly: Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)
Syntax
'Declaration
Public Function Contains ( _
index As Object _
) As Boolean
'Usage
Dim instance As Configurations
Dim index As Object
Dim returnValue As Boolean
returnValue = instance.Contains(index)
public bool Contains(
Object index
)
public:
bool Contains(
Object^ index
)
member Contains :
index:Object -> bool
public function Contains(
index : Object
) : boolean
Parameters
- index
Type: System.Object
The name, identity, ID, or index of the Configuration object to locate in the collection.
Return Value
Type: System.Boolean
A Boolean that indicates whether the collection can be accessed by name, identity, ID, or index. A value of true indicates that the collection can be accessed by using the syntax Configurations[index]. A value of false indicates that indexing cannot be used to retrieve items from the Configurations collection; using this property throws an exception.
Examples
The following code example uses the Contains method to see if item syntax is available.

using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
namespace Configurations_API
{
class Program
{
static void Main(string[] args)
{
Package p = new Package();
Configuration conf1 = p.Configurations.Add();
conf1.ConfigurationString = "Conf1 Configuration String";
conf1.ConfigurationType = DTSConfigurationType.EnvVariable;
conf1.Description = "Some description for Conf1 configuration";
conf1.Name = "Conf1";
conf1.PackagePath = "A Variable Name in configuration Conf1";
Configuration conf2 = p.Configurations.Add();
conf2.ConfigurationString = "Conf2 Configuration String";
conf2.ConfigurationType = DTSConfigurationType.ConfigFile;
conf2.Description = "Some description for Conf2 configuration";
conf2.Name = "Conf2";
conf2.PackagePath = "A Variable Name in configuration Conf2";
Configuration conf3 = p.Configurations.Add();
conf3.ConfigurationString = "Conf3 Configuration String2";
conf3.ConfigurationType = DTSConfigurationType.RegEntry;
conf3.Description = "Conf3 description for Conf3 configuration2";
conf3.Name = "Conf3";
conf3.PackagePath = "A Variable Name in configuration Conf3";
// Use Contains to see if item syntax is available.
Boolean configContains = p.Configurations.Contains("Conf3");
if (configContains)
{
// Use the item syntax of Configurations[x].
String myName = p.Configurations[0].Name;
Console.WriteLine("Name of configuration at position 0 is {0}", myName);
}
else
{
Console.WriteLine("Contains returned {0}", configContains);
}
Console.WriteLine();
}
}
