How to get Table Name of mapped entity in Entity Framework Core

EF Core 5 version

EF Core 5 "now allows an entity type to be mapped to both a table and a view simultaneously".

I don't fully understand this, but it adds complications to finding table names.

For my use case I actually wanted the name of a view, so by checking for TableName and ViewName I could throw an error if the entity supplied was for the wrong type.

var entityType = typeof(Customer);
var modelEntityType = context.Model.FindEntityType(entityType);

string tableName = modelEntityType.GetSchemaQualifiedTableName();
string viewName = modelEntityType.GetSchemaQualifiedViewName();

if (tableName != null) 
{
   throw new Exception("The Entity " + entityName + " represents a table and not a view");
}

Using the Microsoft.EntityFrameworkCore.Relational package in 2.X:

var mapping = dbContext.Model.FindEntityType(typeof(YourEntity)).Relational();
var schema = mapping.Schema;
var tableName = mapping.TableName;

This assumes that dbContext is a instance of class that inherits from DbContext and that you have YourEntity configured there.

Note that in EF Core 3.X, [.Relational() provider extensions have been replaced] (https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-3.0/breaking-changes#provider) with getters and so you can now access the schema as follows:

var entityType = dbContext.Model.FindEntityType(typeof(YourEntity));
var schema = entityType.GetSchema();
var tableName = entityType.GetTableName();

You can Use this static class

public static class AttributeReader
{
    //Get DB Table Name
    public static string GetTableName<T>(DbContext context) where T : class
    {
        // We need dbcontext to access the models
        var models = context.Model;

        // Get all the entity types information
        var entityTypes = models.GetEntityTypes();

        // T is Name of class
        var entityTypeOfT = entityTypes.First(t => t.ClrType == typeof(T));

        var tableNameAnnotation = entityTypeOfT.GetAnnotation("Relational:TableName");
        var TableName = tableNameAnnotation.Value.ToString();
        return TableName;
    }

}

For example, we have Person class that entity name in database is People, we can get people from person class.

var TblName= AttributeReader.GetTableName<YourModel>(YourContext);
