<p>This example demonstrates how to access parameters and set their values using the collection.</p>
<pre><code class="lang-csharp">// Load a page report
PageReport pageReport = new PageReport(new FileInfo("Report1.rdlx"));
pageReport.Document.Load();

// Check if parameter exists before accessing
if (pageReport.Document.Parameters.Contains("EmployeeID"))
{
    var singleParam = pageReport.Document.Parameters["EmployeeID"];
    // Scenario A: Setting a value for a single-value parameter
    singleParam.CurrentValue = 12345;
}

if (pageReport.Document.Parameters.Contains("Regions"))
{
    var multiParam = pageReport.Document.Parameters["Regions"];
    // Scenario B: Setting values for a multi-value parameter
    multiParam.CurrentValue = new string[] { "North", "South" };
}

// 3. Iterating through parameters
foreach (var param in pageReport.Document.Parameters)
{
    Console.WriteLine($"Name: {param.Name}, Value: {param.CurrentValue}");
