How do I access a C# string on my aspx page?

Question

I have declared a String on code-behind like so:

String myString = "Hi SO!";

How do I then print this on my aspx page?

<%= myString %> doesn't appear to be working.

CS0103: The name 'myString' does not exist in the current context

Answer 1

This may depend on where you have declared your string.

Make sure you are not declaring your string inside a method, the string should be a global variable inside the class

Also ensure the string is protected or public

Answer 2

确保您的字符串是受保护的或公共的，以便后代类可以看到它。

Answer 3

The access modifier needs to be at least protected .

protected String myString = "Hi SO!";

The reason behind is that each .aspx page inherits from the code-behind class.

Answer 4

The easiest way I've found to do this is create the string in my code behind page, then add a label on the aspx page. On the code behind page, you will need to write some code like this:

string myString = "some value";
label1.Text = myString;

Make sure this is in the Page_Load event in the code behind page, depending on what you are trying to do. In my case I wanted the string to be called at runtime when the page loads up.
