How to Use FontFamily in a concise manner

I'm new to C# programming and I have a function involving FontFamily. The code seems to work fine but I wanted it written in a more concise manner.
I searched online but seems unable to get the right solution. The following code is what I currently have.
public FontFamily[] FontFamilyExt()
{
FontFamily[] f =
{new FontFamily(_fnt[0]),
new FontFamily(_fnt[1]),
new FontFamily(_fnt[2]),
new FontFamily(_fnt[3]),
new FontFamily(_fnt[4]),
new FontFamily(_fnt[5]),
new FontFamily(_fnt[6]),
new FontFamily(_fnt[7]),
new FontFamily(_fnt[8]),
new FontFamily(_fnt[9]),
new FontFamily(_fnt[10]),
new FontFamily(_fnt[11]),
new FontFamily(_fnt[12]),
new FontFamily(_fnt[13]),
new FontFamily(_fnt[14]),
new FontFamily(_fnt[15]),
new FontFamily(_fnt[16]),
new FontFamily(_fnt[17]),
new FontFamily(_fnt[18]),
new FontFamily(_fnt[19]),
new FontFamily(_fnt[20]),
new FontFamily(_fnt[21]),
new FontFamily(_fnt[22]),
new FontFamily(_fnt[23]),
new FontFamily(_fnt[24]),
new FontFamily(_fnt[25]),
new FontFamily(_fnt[26]),
new FontFamily(_fnt[27]),
new FontFamily(_fnt[28]),
new FontFamily(_fnt[29]),
new FontFamily(_fnt[30]),
new FontFamily(_fnt[31])
};
return f;
}
I am looking for something that works similarly but uses less codes. Thank you in advance.

You could use a loop as recommended. You could also use Enumerable.Range, which basically creates a loop under the covers, but will put the code into one line. Something like:
using System.Linq;
public FontFamily[] FontFamilyExt()
{
return Enumerable.Range(0, 32).Select(x => new FontFamily(_fnt[x])).ToArray();
}

You can try this:
public FontFamily[] FontFamilyExt()
{
FontFamily[] f = new FontFamily[32];
for ( int index = 0; index <= 31; index++ )
f[index] = new FontFamily(_fnt[index]);
return f;
}

Nesting XML Tags using Linq with Data From DB

I am trying to build an XML document using Linq, XElement and data from Database,
It's working kinda, but in my XML, I want to close the tag and start a new tag and get the results from the query to populate into for the Tag, it is complaining that my variable r in the tag is unresolved, how can I make this work, or is there a better way of building the XML. All the child elements should be under the parent , having two children and , which has their own set of children.
Here is the code below
public void GenerateXML(int id, string site, string state, string country, string bFn, string bLn, string sFn, string sLn)
{
var results = (from o in _db.Orders
where o.OrderId == id
select o).ToList();
var xmlDoc = new XElement("Order",
from r in results
select
new XElement("OrderHeader",
new XElement("SiteId", site),
new XElement("OrderId", r.OrderId),
new XElement("Time", r.OrderDate.Value),
new XElement("Subtotal", r.SubTotal),
new XElement("Shipping", ""),
new XElement("SalesTax", r.SalesTax),
new XElement("Total", r.Total),
new XElement("PaymentAmount", ""),
new XElement("PaymentMethod", ""),
new XElement("ArchiTypeAcctNum", "20001"),
new XElement("TaxExempt", r.TaxExempt),
new XElement("SpecialInstructions", r.SpecialInstructions),
new XElement("BillTo",
new XElement("BillEmail", r.BillToEmail),
new XElement("FirstName", bFn),
new XElement("LastName", bLn),
new XElement("CompanyName", r.BillCompany),
new XElement("Address1", r.BillToAddress),
new XElement("City", r.BillToCity),
new XElement("State", state),
new XElement("Country", country),
new XElement("Zip", r.BillToZip),
new XElement("Phone", r.BillToPhoneNumber)),
new XElement("ShipTo",
new XElement("FirstName", sFn),
new XElement("LastName", sLn),
new XElement("CompanyName", r.ShipCompany),
new XElement("Address1", r.ShipToAddress),
new XElement("City", r.ShipToCity),
new XElement("State", state),
new XElement("Country", country),
new XElement("Zip", r.ShipToZip),
new XElement("Phone", r.ShipToPhoneNumber))),
new XElement("Items",
from i in r.Items
select new XElement("Item",
new XElement("SKU", i.SkuNumber),
new XElement("PROD_Name", i.ProductName),
new XElement("Description", i.Description),
new XElement("Attributes", i.Attributes),
new XElement("Quantity", i.Quantity),
new XElement("UnitPrice", i.UnitPrice),
new XElement("InkColor", i.InkColor)))
);
xmlDoc.Save(Server.MapPath(#"~/Xml/Orders.xml"));
RedirectToAction("Save");
}

I wrote an extension for same purpose. I think much easier . you can just use as orders.EntityToXml();
public static class XmlExtensions
{
public static bool EntityToXml<T>(this T entity, string filePath)
{
if (string.IsNullOrEmpty(filePath))
{
throw new ArgumentNullException(nameof(filePath));
}
var dir = Path.GetDirectoryName(filePath);
if (string.IsNullOrEmpty(dir))
{
throw new ArgumentNullException(nameof(filePath));
}
if (!Directory.Exists(dir))
{
Directory.CreateDirectory(dir);
}
var serializer= new System.Xml.Serialization.XmlSerializer(typeof(T));
using (var stream = new StreamWriter(filePath))
{
serializer.Serialize(stream , entity);
return true;
}
}
}

Linq to XElement Preparation with some condtions

private XElement GetClinicalClientPrice(int invid)
{
using (MyDatabase db = new MyDatabase())
{
return new XElement("CLINICALCLIENTPRICE",
from ccp in db.TblClinicalClientPrice
where ccp.INVENTORY_ID == invid
select new XElement("Record",
new XElement("ITEM_ID",ccp.ITEM_ID),
new XElement("INVENTORY_ID", ccp.INVENTORY_ID),
new XElement("ITEM_DESCRIPTION", ccp.ITEM_DESCRIPTION),
new XElement("SUPPLIER_CAT", ccp.SUPPLIER_CAT),
new XElement("NDC_CODE", ccp.NDC_CODE),
new XElement("ITEM_NUMBER", ccp.ITEM_NUMBER),
new XElement("UOM", ccp.UOM),
new XElement("CONVERSION_FACTOR", ccp.CONVERSION_FACTOR),
new XElement("MANUFACTURER", ccp.MANUFACTURER),
new XElement("SESSION_ID", ccp.SESSION_ID),
new XElement("USERNAME", ccp.USERNAME),
new XElement("ENTRY_TIME", ccp.ENTRY_TIME),
new XElement("COST", ccp.COST),
new XElement("CLIENT_INPUT_ID", ccp.CLIENT_INPUT_ID),
new XElement("MHS_ITEM_ID", ccp.MHS_ITEM_ID),
new XElement("GUID", ccp.GUID),
new XElement("UNIQUE_ID", ccp.UNIQUE_ID),
new XElement("SUPPLIER_CAT_MODIFIED", ccp.SUPPLIER_CAT_MODIFIED),
new XElement("SIZE", ccp.SIZE),
new XElement("STRENGTH", ccp.STRENGTH)
));
}
}
I am getting (DateTime) Null value exception when I am inserting above resulted XElement into data base.
My Example is : stackoverflow.com/a/21163312/3121707

Getting Country Calling Code in .NET Framework

In my program I need to get currency symbol and country calling code for specific countries.
I can get currency symbol from RegionInfo class
new RegionInfo(abbreviation).CurrencySymbol
But I cannot find a way to get country calling code from .NET Framework.

Years too late for the original poster, but if someone stumbles across this & wants a bit of code to save creating themselves a list of dial codes from Wikipedia, an open source project (of mine) has this C# file:

If you're talking about phone calling codes you have to build a look-up table.
I would recommend looking this list of calling codes: Wikipedia

There's also quite a handy ReST API for this. I'd suggest copying the data locally into a json file or whatever rather than relying on a third-party service.

Build a Yaml document dynamically from c#

Is it possible to build a Yaml document dynamically from c# with Yaml.DotNet or another library?
I understand how this can be done using serialisation, however that requires starting with an object structure.
I'm looking to find a way to create the Yaml document nodes on the fly as you would with Xml using the XElement.Add(object) method for example.

You can do that using YamlDotNet. You start by creating a YamlStream, add one or more document to it, then you can add sequences, mappings and scalars to it.
Here is an example on how to do it:
var address = new YamlMappingNode(
new YamlScalarNode("street"),
new YamlScalarNode("123 Tornado Alley\nSuite 16") { Style = YamlDotNet.Core.ScalarStyle.Literal },
new YamlScalarNode("city"),
new YamlScalarNode("East Westville"),
new YamlScalarNode("state"),
new YamlScalarNode("KS")
) { Anchor = "main-address" };
var stream = new YamlStream(
new YamlDocument(
new YamlMappingNode(
new YamlScalarNode("repeipt"),
new YamlScalarNode("Oz-Ware Purchase Invoice"),
new YamlScalarNode("date"),
new YamlScalarNode("2007-08-06"),
new YamlScalarNode("customer"),
new YamlMappingNode(
new YamlScalarNode("given"),
new YamlScalarNode("Dorothy"),
new YamlScalarNode("family"),
new YamlScalarNode("Gale")
),
new YamlScalarNode("items"),
new YamlSequenceNode(
new YamlMappingNode(
new YamlScalarNode("part_no"),
new YamlScalarNode("A4786"),
new YamlScalarNode("descrip"),
new YamlScalarNode("Water Bucket (Filled)"),
new YamlScalarNode("price"),
new YamlScalarNode("1.47"),
new YamlScalarNode("quantity"),
new YamlScalarNode("4")
),
new YamlMappingNode(
new YamlScalarNode("part_no"),
new YamlScalarNode("E1628"),
new YamlScalarNode("descrip"),
new YamlScalarNode("High Heeled \"Ruby\" Slippers"),
new YamlScalarNode("price"),
new YamlScalarNode("100.27"),
new YamlScalarNode("quantity"),
new YamlScalarNode("1")
)
),
new YamlScalarNode("bill-to"), address,
new YamlScalarNode("ship-to"), address,
new YamlScalarNode("specialDelivery"),
new YamlScalarNode("Follow the Yellow Brick\n" +
"Road to the Emerald City.\n" +
"Pay no attention to the\n" +
"man behind the curtain.")
{
Style = YamlDotNet.Core.ScalarStyle.Literal
}
)
)
);

I've now worked out how to do this using Yaml.Net. The YamlStream needs to be loaded with some initial content using the Load() method.
const string initialContent = "---\nversion: 1\n...";
var sr = new StringReader(initialContent);
var stream = new YamlStream();
stream.Load(sr);
You can then cast the RootNode of the YamlDocument to YamlMappingNode which has an Add method.
var rootMappingNode = (YamlMappingNode)stream.Documents[0].RootNode;
rootMappingNode.Add("shout", "yay!");
You can then add a variety of node types before saving:
var props = new YamlMappingNode();
props.Add("prop1", "value1");
props.Add("prop2", "value2");
rootMappingNode.Add("itemWithProps", props);
var props2 = new YamlMappingNode();
props2.Add("prop1", "value1");
props2.Add("prop2", "value2");
var props3 = new YamlMappingNode();
props3.Add("prop1", "value1");
props3.Add("prop2", "value2");
var seq = new YamlSequenceNode();
seq.Add(props2);
seq.Add(props3);
rootMappingNode.Add("sequenceOfItems", seq);
var col = new YamlSequenceNode();
col.Style = SequenceStyle.Flow;
col.Add("a");
col.Add("b");
col.Add("c");
var seqMapping = new YamlMappingNode();
seqMapping.Add("collection", col);
seq.Add(seqMapping);
using (TextWriter writer = File.CreateText("C:\\temp\\test.yaml"))
stream.Save(writer, false);
The output from this example is:
version: 1
shout: yay!
itemWithProps:
prop1: value1
prop2: value2
sequenceOfItems:
- prop1: value1
prop2: value2
- prop1: value1
prop2: value2
- collection: [a, b, c]
...
Thanks to #Antoine Aubry for creating Yaml.Net and vaguely pointing me in right direction.
