How to declare a Globar Variable in C#?

Praveen Kumar

Currently I am declaring Global variable as

public static string SerialNo;

I am set value into Declared SerialNo in Page_Load event.

I am using this serial no in multiple methods.

But my problem is

Suppose there is multiple persons accessing the same page at the same time In my application mutiple tabs available like Employee Details, Salary Details, ....

A user has two records in Employee Details tab.

B user updated data in Employee Details tab.

Both are using different serial no's but accessing same page.

Now A user refresh Employee Details tab he got 3 records(3rd record updated by B user).

I am thinking the problem is not declaring SerialNo variable properly.

Please help me how to declare that SerialNo variable Globally.

try declare like this, but not in page load event,
yo can declare outside function
inside class
public static string SerialNo{get;set;}

Hi, sorry to say but I'm not getting your point yet after reading your problem 3 times.
Global variable =>variable accessible anywhere.
The global variable can be accessed from any function or class within the namespace.
In your problem statement:
User A is performing select operation and not performing any CRUD operation.
User B is performing UPDATE operation based on the "SerialNo" so No new record will be inserted into the table.hence User A will see only two records (updated record).

If this solution suffice your problem statement then please acknowledge or restate your problem statement so that I can help you.
