如何在C＃中以所有形式提供字符串

Question

I'm using Compact Framework 2.0 for an application in Windows CE 5.0 device with multiple forms.

I have to use a connection string in almost all the forms in order to access to the database:

string conString = "Data Source=\\Program Files\\myproject\\database.sdf";

I would like to know if it's possible to make this connection string somehow "global" in order to be written only once and accessible from all the forms.

Answer 1

As per @Steven's comment, you should really add this in the config file, however see below for an example of what you asked for.

Create a class for it and make it a public const field.

public static class Globals
{
    public const string conString = "Data Source=\\Program Files\\myproject\\database.sdf"; 
}

Then in your forms (or anywhere else) you could access it as Globals.conString .

For more flexibility you can use readonly keyword. Readonly members are initilized at runtime and can hold complex objects.

public class DataBaseConfiguration
{
     public readonly String conStr;

     public DataBaseConfiguration(String conString)
     {
          this.conString = conString;
     }
}
