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;
}

c# CodeDOM - Initialize array

I'm trying to create a simple dll runtime, using CodeDOM.
I have quite understand what I need to finish this simple test application.
I need to create with CodeDOM object this statement:
List<string> test = new List<string>() {"A", "B", ... }
I'm just having this statement for declaration of a List of n values, but find nowhere the instructions for reach what I need.
This is my actual code:
CodeCompileUnit compileUnit = new CodeCompileUnit();
CodeNamespace samples = new CodeNamespace("ClassLibrary1");
compileUnit.Namespaces.Add(TestNamespace);
samples.Imports.Add(new CodeNamespaceImport("System"));
samples.Imports.Add(new CodeNamespaceImport("System.Collections.Generic"));
samples.Imports.Add(new CodeNamespaceImport("System.Text"));
CodeTypeDeclaration _class = new CodeTypeDeclaration("TestClass");
CodeMemberField _field = new CodeMemberField();
_field.Attributes = MemberAttributes.Private;
_field.Name = "_testMember";
_field.Type = new CodeTypeReference(typeof(List<string>));
//This is where I cannot understand how to insert the values
_field.InitExpression = new CodeObjectCreateExpression(new CodeTypeReference(typeof(List<string>)), new CodePrimitiveExpression(64));
class1.Members.Add(_field);
How to initialize a list (or an array) with some default values?
Thank you in advance.

As suggested, the answer lies in CodeArrayCreateExpression.
Here is the completed (working) code snippet:
CodeCompileUnit compileUnit = new CodeCompileUnit();
CodeNamespace samples = new CodeNamespace("ClassLibrary1");
compileUnit.Namespaces.Add(samples);
samples.Imports.Add(new CodeNamespaceImport("System"));
samples.Imports.Add(new CodeNamespaceImport("System.Collections.Generic"));
samples.Imports.Add(new CodeNamespaceImport("System.Text"));
CodeTypeDeclaration _class = new CodeTypeDeclaration("TestClass");
CodeMemberField _field = new CodeMemberField();
_field.Attributes = MemberAttributes.Private;
_field.Name = "_testMember";
_field.Type = new CodeTypeReference(typeof(List<string>));
var initialiseExpression = new CodeArrayCreateExpression(
new CodeTypeReference(typeof(string)),
new CodePrimitiveExpression("A"),
new CodePrimitiveExpression("B"),
new CodePrimitiveExpression("C"));
_field.InitExpression = new CodeObjectCreateExpression(new CodeTypeReference(typeof(List<string>)), initialiseExpression);
_class.Members.Add(_field);
The important part is the new initialiseExpression variable that defines the array.

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;
}
}
}

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.

Errors while attempting to generate code using Codedom

My goal: To create a windows form application (executable) through the use of CodeDom. By this I mean I would like a form (with some code behind the form) and turn it into an executable file (as if I had gone into Visual Studio and clicked "Build" > "Build File"). Admittingly, I found this example online and I have since lightly modified it. I am getting errors while trying to generate this code - errors that I have never seen before. Furthermore, I could not find these errors on Google (odd right?)...
Here is the error I am getting:

You have many instances where you create an empty CodeExpression, such as in the constructor code:
// Create the constructor and add code
CodeConstructor Constructor = new CodeConstructor();
Constructor.Statements.Add(
new CodeMethodInvokeExpression(
new CodeThisReferenceExpression(), "InitializeComponent", new CodeExpression() { }));
If you don't want to pass any parameters to the method (which is the case in the code above), simply don't pass anything (CodeMethodInvokeExpression constructor takes a params[] array, so if you don't pass anything, it means that it receives an empty array):
// Create the constructor and add code
CodeConstructor Constructor = new CodeConstructor();
Constructor.Statements.Add(
new CodeMethodInvokeExpression(
new CodeThisReferenceExpression(),
"InitializeComponent"));

in case above code is not spitting the required code make sure you are closed the IndentedTextWriter e.g. writer.Close() enjoy..

CodeMemberMethod DisposeMethod = new CodeMemberMethod();
DisposeMethod.Name = "Dispose";
DisposeMethod.ReturnType = new CodeTypeReference(typeof(void));
DisposeMethod.Attributes = MemberAttributes.Override | MemberAttributes.Private;
DisposeMethod.Parameters.Add(new CodeParameterDeclarationExpression(typeof(bool), "disposing"));
myDesignerClass.Members.Add(DisposeMethod);
CodeConditionStatement cstif2 = new CodeConditionStatement();
CodeExpression dis = new CodeVariableReferenceExpression("disposing");
CodeExpression comp = new CodeVariableReferenceExpression("components");
cstif2.Condition = new CodeBinaryOperatorExpression(dis, CodeBinaryOperatorType.BooleanAnd, new CodeBinaryOperatorExpression(dis, CodeBinaryOperatorType.IdentityInequality, new CodePrimitiveExpression(null)));
CodeExpression dispos = new CodeMethodInvokeExpression(comp, "Dispose", new CodeExpression[] { });
cstif2.TrueStatements.Add(dispos);
DisposeMethod.Statements.Add(cstif2);
CodeExpression bdispos = new CodeMethodInvokeExpression(new CodeBaseReferenceExpression(), "Dispose", new CodeExpression[] { });
DisposeMethod.Statements.Add(bdispos);

Replace () after CodeExpression with [] and error will vanish.
