reading ColumnAttribute data

[lausivcid]

Hi,

How can ColumnAttribute data be read from xxDataClasses.cs Columns
like this?

[Column(Storage="_Name", DbType="VarChar(256) NOT
NULL", CanBeNull=false)]
public string Name
{
get
{
return this._Name;
}
set
{
if ((this._Name != value))
{
this.OnNameChanging(value);
this.SendPropertyChanging();
this._Name = value;
this.SendPropertyChanged("Name");
this.OnNameChanged();
}
}
}
Attribute.GetCustomAttribute(this.Name.GetType().M odule,typeof(System.Data.Linq.Mapping.ColumnAttrib ute))
returned null,
Attribute.GetCustomAttributes(this.Name.GetType(). Module) returned
only the System.Security.UnverifiableCodeAttribute attribute.
Specifically I want to parse DbType to get the maximum length of the
column. Is there any other way to find the column width?

Thanks,
lausivcid

lausivcid,

Well, you have applied the attribute to a property, so you have to get
the PropertyInfo for that property (Name) and then call GetCustomAttributes
on that.

Thanks! For

[Column(Storage="_Name", DbType="VarChar(256) NOT
NULL", CanBeNull=false)]
public string Name
{
get
{
return this._Name;
}
set
{
if ((this._Name != value))
{
this.OnNameChanging(value);
this.SendPropertyChanging();
this._Name = value;
this.SendPropertyChanged("Name");
this.OnNameChanged();
}
}
}

The class tyoe for this property is "job". The below code gets the
DbType string I am looking for.

foreach (MemberInfo mi in
job.GetType().GetMembers())
{
string attrib=
((System.Data.Linq.Mapping.ColumnAttribute)(mi.Get CustomAttributes(false)[0])).DbType;
}
