Webmatrix - setting variable from querystring as int

Question

i am currently looking for a way to set the amount of results i show depending on if a querystring has been set.

So basically, i first want to check to see if a querystring called pagesize is present. If that is set to a value of 10, then i need it to change a variable to 10. If it's not set, then the variable is set to 6.

Here's my current code:

var pageSize = 0;

if (Request.QueryString["pagesize"].AsInt = 10)
{
    pageSize = 10;
}
else
{
    pageSize = 6;
}

The error i'm getting back is "Cannot assign to 'AsInt' because it is a 'method group'"

Any ideas?

Answer 1

As the error suggests, the AsInt method is an extension method. Just add some brackets to call the method, also missing an extra =, as per the comments:

var pageSize = 0;

if (Request.QueryString["pagesize"].AsInt() == 10)
{
    pageSize = 10;
}
else
{
    pageSize = 6;
}

You can further simplify your code by taking advantage of the conditional operator. The following line achieves the same result:

var pageSize = Request.QueryString["pagesize"].AsInt() == 10 ? 10 : 6;
