can I have any Paypal Sandbox Integration step by step for ASP.net c# (for Website, web application) with an example?

What I have tried:

string redirectUrl = "";

redirectUrl += "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_xclick&business=" + ConfigurationManager.AppSettings["paypalemail"].ToString();

redirectUrl += "&first_name=name";

redirectUrl += "&item_name=" + Name;

redirectUrl += "&amount=" + Price;

redirectUrl += "&business=Paypalmail";

redirectUrl += "&quantity=1";

redirectUrl += "&return=" + ConfigurationManager.AppSettings["SuccessURL"].ToString();

redirectUrl += "&cancel_return=" + ConfigurationManager.AppSettings["FailedURL"].ToString();

Response.Redirect(redirectUrl);

Success URL, and Failed URL are defined in Web.config.

I'd suggest asking PayPal first and going to their dev site.

I don't know anything about PayPal integration, but is it possible that having the business= specified twice is confusing things?
Also, are the values you are including in the redirectUrl are appropriately Url encoded? (See HttpUtility.UrlEncode Method (String) (System.Web)[^] and/or HttpUtility.UrlPathEncode Method (String) (System.Web)[^].)

The code you have is a bit sloppy ;-)
Here's how I'd structure it (I'm not addressing the encoding potential issue.)
Option 1:

C#

const string redirectUrlFormat = 
"https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_xclick&business={0}" + 
"&first_name=name" +
"&item_name={1}" +
"&amount={2}" +
// "&business=Paypalmail"    // This was the duplication!!!
"&quantity=1" +
"&return={3}"
"&cancel_return={4}";
string redirectUrl = string.Format(redirectUrlFormat,
                                   ConfigurationManager.AppSettings["paypalemail"],
                                   Name, Price,
                                   ConfigurationManager.AppSettings["SuccessURL"],
                                   ConfigurationManager.AppSettings["FailedURL"]);
Response.Redirect(redirectUrl);

Option 2:

C#

StringBuilder redirectUrl = new StringBuilder();

redirectUrl.Add("https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_xclick&business=");
redirectUrl.Add(ConfigurationManager.AppSettings["paypalemail"]);
redirectUrl.Add("&first_name=name&item_name=");
redirectUrl.Add(Name);
redirectUrl.Add("&amount=");
redirectUrl.Add(Price);
redirectUrl.Add("&quantity=1&return=");
redirectUrl.Add(ConfigurationManager.AppSettings["SuccessURL"]);
redirectUrl.Add("&cancel_return=");
redirectUrl.Add(ConfigurationManager.AppSettings["FailedURL"]);

Response.Redirect(redirectUrl.ToString());
