I need to get the list of All tables in the Entity Data Framework.
I know that in Linq2SQL we can use something like this. var dataContext = new DataContext(); var dataContextTableNames = (from tables in dataContext.Mapping.GetTables() select tables.TableName).ToList();
But, I need to get list of all tables in Entity Data Framework. There is any 开发者_开发百科work around to get similar list in Entity Data Framework.
Thanks in advance.
[Edit]
Perhaps this can be of use to find the number of objects in Storage space
var count = GetEntitySetCount(myObjectContext.MetadataWorkspace);
public static int GetEntitySetCount(MetadataWorkspace workspace)
{
var count = 0;
// Get a collection of the entity containers from storage space.
var containers = workspace.GetItems<EntityContainer>(DataSpace.SSpace);
foreach(var container in containers)
{
//Console.WriteLine("EntityContainer Name: {0} ",
// container.Name);
foreach(var baseSet in container.BaseEntitySets)
{
if(baseSet is EntitySet)
{
count++;
//Console.WriteLine(
// " EntitySet Name: {0} , EntityType Name: {1} ",
// baseSet.Name, baseSet.ElementType.FullName);
}
}
}
return count;
}
To retrieve the number of tables in the database, you can do the following in .Net 4.0
myObjectContext.ExecuteStoreQuery<int>(
"SELECT COUNT(*) from information_schema.tables WHERE table_type = 'base table'");
Using .Net 3.5
var connection = ((EntityConnection)myObjectContext.Connection).StoreConnection as SqlConnection;
var cmd = new SqlCommand("SELECT COUNT(*) from information_schema.tables WHERE table_type = 'base table'", connection);
connection.Open();
var count = (int)cmd.ExecuteScalar();
connection.Close();
