The hatch fill style is used to fill an object with a hatch pattern. It is represented by an instance of the NHatchFillStyle class. The following examples applies a hatch fill style to an object:
| C# |
Copy Code
|
|---|---|
someObject.FillStyle = new NHatchFillStyle(HatchStyle.Cross, Color.White, Color.Black);
|
|
| Visual Basic |
Copy Code
|
|---|---|

There are 48 predefined gradient styles, which are enumerated by the System.Drawing.Drawing2D.HatchStyle enumeration. The gradient style is controlled by the Style property.
The following table shows the different hatch pattern styles with a White foreground and Black background color.

You can use the table above as a visual reference for the hatch pattern style. To get the pattern constant all you have to do is to concatenate the words in the pattern name columns. For example if you want to achieve a "Zig Zag" pattern you must use the following code:
| C# |
Copy Code
|
|---|---|
someObject.FillStyle = new NHatchFillStyle(HatchStyle.ZigZag, Color.White, Color.Black);
|
|
| Visual Basic |
Copy Code
|
|---|---|
someObject.FillStyle = new NHatchFillStyle(HatchStyle.ZigZag, Color.White, Color.Black)
