SqlHierarchyId.ToString Method
Returns the canonical string representation of a SqlHierarchyId node from a SqlHierarchyId value.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax
'Declaration
<SqlMethodAttribute(DataAccess := DataAccessKind.None, SystemDataAccess := SystemDataAccessKind.None, _

'Usage
Dim instance As SqlHierarchyId

Return Value
Type: System.String
String
Remarks
Called implicitly when a conversion from a SqlHierarchyId data type to a string type occurs.
Acts as the opposite of Parse.
Examples
DECLARE @StringValue AS nvarchar(4000), @hierarchyidValue AS hierarchyid
SET @StringValue = '/1/1/3/'
SET @hierarchyidValue = 0x5ADE
SELECT hierarchyid::Parse(@StringValue) AS hierarchyidRepresentation,
@hierarchyidValue.ToString() AS StringRepresentation ;
