EF5 How to get the schema and table name from a dbSet

Question

I want to write an extension that should get the table name and the schema from a dbSet.

public static string GetTableInfo<T>(this DbSet<T> dbSet) where T : class
{
    var tableName = ?? // how to retrieve if from the dbSet ? 
    var schemaName = ?? // how to retrieve if from the dbSet ? 

    return $"{schemaName}.{tableName}";
}

Usage :

var tableInfo = _libraryContext.Books.GetTableInfo();
// tableInfo should return "dbo.Book"

how i can get the table and schema names directly from the DbSet ?

See if you can take the following and adapt to your code as this is close but not exactly what you wanted.

In the dbContext

modelBuilder.HasDefaultSchema("dbo");

Extension method

public static class EntityHelpers
{
    public static string GetTableNameWithScheme<T>(this DbContext context) where T : class
    {
        var entityType = context.Model.FindEntityType(typeof(T));
        var schema = entityType.GetDefaultSchema();
        return $"{schema ?? "(unknown)"}.{entityType.GetTableName()}";
    }
}

Example

using var context = new YourContext();
Console.WriteLine(context.GetTableNameWithScheme<YourModel>());
