InMemoryDataStore.GetConnectionString(String) Method

Returns a connection string that can be used to create an InMemoryDataStore instance.

Namespace: DevExpress.Xpo.DB

Assembly: DevExpress.Xpo.v21.1.dll

NuGet Package: DevExpress.Xpo

Declaration

C#

public static string GetConnectionString(
    string path
)

VB.NET

Public Shared Function GetConnectionString(
    path As String
) As String

Parameters

Name	Type	Description
path	String	A string value that specifies the name (including the path) of the XML document that includes both schema and data.

Returns

Type	Description
String	A string containing the connection string to an InMemoryDataStore instance.

Remarks

The value returned by this method can be used to initialize a Session’s connection string (for instance, via the Session.ConnectionString or XpoDefault.ConnectionString property).

If you pass a null reference via the path parameter, the GetConnectionString method will return a connection string to create an InMemoryDataStore instance that is not bound to an XML file.
