How to draw squares and assign the color property dynamically (PDFsharp)?

Question

I am using PDFsharp to export a chart legend. I am using a for loop and a table to display the properties. There is actually only one property: the Subdivision name. The object has the right RGB color to use. How can I draw squares next to it just as chart legends display the series? Forgive me for the variable names, I am going off a example.

//Writting Table Header Text
textformater.DrawString(" Color", tableheader, XBrushes.Black, snoColumn);
textformater.DrawString(" Subdivision Name", tableheader, XBrushes.Black, snoStudentName);

foreach (var item in data)
{
    y = y + 30;
    XRect snoColumnVal = new XRect(35, y, 70, height);
    XRect snoStudentNameVal = new XRect(100, y, 250, height);
    textformater.DrawString(item.Color, tableheader, XBrushes.Black, snoColumnVal);
    textformater.DrawString(item.Name, tableheader, XBrushes.Black, snoStudentNameVal);

}

Here is the output:

this is what I need it to look like

Answer 1

I used this struct for the demo:

struct RowItem
{
    public int R, G, B;
    public string Text;
}

Here's my test data:

var data = new[]
               {
                   new RowItem{R = 255, G = 0, B = 0, Text = "Red row"},
                   new RowItem{R = 0, G = 255, B = 0, Text = "Green row"},
                   new RowItem{R = 255, G = 255, B = 0, Text = "Yellow row"},
                   new RowItem{R = 0, G = 0, B = 255, Text = "Blue row"},
                   new RowItem{R = 255, G = 0, B = 255, Text = "Purple row"},
                   new RowItem{R = 0, G = 255, B = 255, Text = "Cyan row"},
                   new RowItem{R = 0, G = 0, B = 0, Text = "Black row"}
               };

And here's the code that does the drawing:

foreach (var item in data)
{
    y = y + 30;
    XRect snoColumnVal = new XRect(35, y, 60, 25);
    XRect snoStudentNameVal = new XRect(100, y, 250, 25);
    var brush = new XSolidBrush(XColor.FromArgb(255, item.R, item.G, item.B));
    gfx.DrawRectangle(XPens.Black, brush, snoColumnVal);
    textformater.DrawString(item.Text, font, XBrushes.Black, snoStudentNameVal);
}

R, G, and B are the color components (range 0 through 255).

Answer 2

Just draw the square like so:

// Create solid brush.
SolidBrush blueBrush = new SolidBrush(Color.Blue);

// Create rectangle.
Rectangle rect = new Rectangle(0, 0, 200, 200);

// Fill rectangle to screen.
e.Graphics.FillRectangle(blueBrush, rect);

Here is how you set the color:

// Create a green color using the FromRgb static method.
Color myRgbColor = new Color();
myRgbColor = Color.FromRgb(0, 255, 0);
return myRgbColor;
