Dynamically declaring variable

Question

Hi,

I was wondering if there is any way to dynamically declare variables using the value of a string.....

I was thinking something like

 

 // Declare Variables
        int VariablestoCreate;
        int counter = 0;
        String VariableBaseName = "RandomVariable";
        String VariableName;

        VariablestoCreate = 10; // This value would change from user to user (which is why I need to dynamic create variables)

        for (int i = 0; i < 10; i++)
        {
          counter = counter + 1;
          VariableName = VariableBaseName + Convert.ToString(counter);

          // and here is where I would want to declare variables dynamically. Lets just say an int here.
          // so I was thinking something on the lines of
          int VariableName.Value(); 
          // So as the loop continues you would end up with ten variables called RandomVariable1, RandomVariable2, ect
          
        }

The reason that I am interested in this is because I wish to dynamically add items (textbox, labels, ect) to my WFA - the number of which would change from user to user.

Is this possible, or am I going to have to think of another way around this?

Thanks

Hi,

Why can t you use HashTable or List or Dictionary to store those values, which will reduce the complexity.

Arrays, Lists, Dictionaries allows you to add any number of values. No Need to specify length, which ideally

suites in your case. If there is any specific reason that you want to declare variables only??

Hi Thomas,

 

You can use a Generic collection to collect the variables, to something like this:

 

        List<String> VariableNames = new List<string>();

        for (int i = 0; i < VariablestoCreate; i++)

        {

          counter = counter + 1;

          VariableName = VariableBaseName + Convert.ToString(counter);

          VariableNames.Add(VariableName); 

        }

        foreach(Control c in Controls )

            if (c.Name.Equals("textBox2"))

                c.Text = VariableNames[1];
