I have a problem with the change tracker in EntityFrame work.
How can I get the Database name from the change tracker?
I implemented my code but It returns just the model name, not the Physical DB name.
Thank you.

What I have tried:

Get physical Db name by change tracker in entityframework

Not to sure what you are looking for, is it:
foreach (var entityType in dbContext.Model.GetEntityTypes())
    var tableName = entityType.GetTableName();
    foreach (var propertyType in entityType.GetProperties())
        var columnName = propertyType.GetColumnName();

I'm using MVC5 and my dbcontext does not have Model.
I just want to show Physical Table Name of current model.

What do you mean you don't have DBContext? Read this:

No, I have Dbcontext for Identity MVC5.

RoleBaseDbContext db = new RoleBaseDbContext();
var s=ContextExtensions.GetTableName<string>(db);

foreach (var ent in this.ChangeTracker.Entries().Where(p => p.State == EntityState.Added || p.State == EntityState.Deleted || p.State == EntityState.Modified))

// For each changed record, get the audit record entries and add them
foreach (All_Log x in GetAuditRecordsForChange(ent, userId))

but I think it dose not exist dbContext.Model.GetEntityTypes().
for mvc5 it exist in asp .net core.

"Change tracking" is not relevant to your question.

The dbContext has a .DataBase "class" property.

The Database class points to a .DbConnection class / object.

The .DbConnection class has a .Database "string" that is the "physical db name".

OP is looking for the table name corresponding to entities. He wrote database instead of table in original post but later in comment said: "I just want to show Physical Table Name of current model."

I am confused on what he means he doesn't have a model for DBContext given he is working on ASP.NET MVC.
