I would like to create a variable which uses another variable outside of a function, like this:
private void tb_TextChanged(object sender, TextChangedEventArgs e)
{
...
}
TextStyle txtstyle = new TextStyle(new SolidBrush(Color.Red), null, FontStyle.Regular); // the variable
private void tb_VisibleRangeChangedDelayed(object sender, EventArgs e)
{
...
}
I want to replace Color.Red in txtstyle with a custom color which is in the applications setting. How can I achieve this?
I would create a private property like this:
private TextStyle myTextStyle
{
get
{
var colorName = "Red";
if(!string.IsNullOrWhiteSpace(ConfigurationManager.AppSettings["myColor"]))
{
colorName = ConfigurationManager.AppSettings["myColor"];
}
return new TextStyle(new SolidBrush(Color.FromName(colorName)), null, FontStyle.Regular);
}
}
you have to add a reference to System.Configuration for this to work.
Since you have declared txtstyle in the class scope, you can access it from within functions that are part of the same class.
I suggest you read up on C# scoping rules.
You can access the settings in this way:
TextStyle txtstyle = new TextStyle(new SolidBrush(Properties.Settings.Default["Color"]), null, FontStyle.Regular); // the variable
