通过Linq来获取数据库中的所有表及其字段名称

static void Main(string[] args)
{

DataClasses1DataContext dc = new DataClasses1DataContext();

Console.WriteLine("Database: {0}", dc.Mapping.DatabaseName);//数据库名称

Console.WriteLine("The table count is {0}",dc.Mapping.GetTables().Count());//表的数目

var tables = from t in dc.Mapping.GetTables()

orderby t.TableName

select t;

foreach (var table in tables)

{

Console.WriteLine("Tablename is :"+table.TableName);//表名称

Console.WriteLine("The column count is :{0}", table.RowType.DataMembers.Count);//字段数目

foreach (var col in table.RowType.DataMembers)

{

Console.WriteLine(""t{0}"t{1}", col.MappedName, col.DbType);//字段名称及字段类型

}

}

Console.WriteLine("This is the end.");

Console.ReadLine();

}
