Hello Chuck,
It depends on where you would like to get information.
1) The simple way is to copy your dbml file into output folder. Then, you
can load that file into XMLDocument instance and retrieve each node by
XMLPath.
For example:
System.Xml.XmlDocument xd = new System.Xml.XmlDocument();
xd.Load("DataClassesName.dbml");
System.Xml.XmlNamespaceManager xnm = new
System.Xml.XmlNamespaceManager(xd.NameTable);
xnm.AddNamespace("dbml",
"
http://schemas.microsoft.com/linqtosql/dbml/2007");
string dbtype =
xd.DocumentElement.SelectSingleNode("//dbml
atabase/dbml:Table[@Name='dbo.T
able_1']/dbml:Type/dbml:Column[@Name='c1']",
xnm).Attributes["DbType"].Value;
2) Another way is to use reflection to access the ColumnAttribute class in
the System.Data.Linq.Mapping namespace.
For example:
Type linqType = typeof(Table_1);
PropertyInfo[] linqProperties = linqType.GetProperties();
foreach (PropertyInfo property in linqProperties)
{
object[] attributes =
property.GetCustomAttributes(typeof(ColumnAttribute), true);
if (attributes.Length > 0)
{
ColumnAttribute attribute = attributes[0] as
ColumnAttribute;
System.Console.WriteLine(attribute.DbType);
}
}
