Can FastMember.ObjectReader take DisplayName into account?

Question

I'm using FastMember.ObjectReader to copy a list of structs to a DataTable, which I then use as the DataSource of a gridview:

struct Foo {
    [DisplayName("title1")]
    public string Bar { get; set; }
}
...
var rows = new List<Foo>();
rows.Add(new Foo { Bar = "somethingsomething" });
DataTable table = new DataTable();
using (var reader = ObjectReader.Create(rows)) {
    table.Load(reader);
}
grid.DataSource = table.DefaultView;

If I select the list itself as the DataSource, the DisplayNames are used as column titles instead of the struct member name:

How can I recreate that when using FastMember.ObjectReader?

Answer 1

Oh, I see what you mean; you want the IDataReader to expose the [DisplayName] in the metadata; however, the primary way that is exposed is via GetSchemaTable(), and AFAIK there is no recognised key to represent [DisplayName]. It would be incorrect to pass that as the name, IMO.

Running a quick test:

var table = new DataTable();
table.Columns.Add("foo").Caption = "bar";
var schema = table.CreateDataReader().GetSchemaTable();

foreach(DataRow row in schema.Rows)
{
    foreach(DataColumn col in schema.Columns)
    {
        Console.WriteLine($"{col.ColumnName}={row[col]}");
    }
    Console.WriteLine();
}

shows that indeed it is unlikely to expect it there:

ColumnName=foo
ColumnOrdinal=0
ColumnSize=-1
NumericPrecision=
NumericScale=
DataType=System.String
ProviderType=
IsLong=False
AllowDBNull=True
IsReadOnly=False
IsRowVersion=False
IsUnique=False
IsKey=False
IsAutoIncrement=False
BaseCatalogName=
BaseSchemaName=
BaseTableName=
BaseColumnName=foo
AutoIncrementSeed=0
AutoIncrementStep=1
DefaultValue=
Expression=
ColumnMapping=1
BaseTableNamespace=
BaseColumnNamespace=

this means that there isn't really anything I can suggest other than to manually populate the .Caption, perhaps use fast-member to get the data.
