Solution 1

ToolStripItemCollection does not support the WHERE query: try doing it with a foreach loop instead.

Solution 2

Try this,

C#

public void SetVisibility(string menuItemText)
{
    foreach (ToolStripMenuItem menuItem in menuStrip1.Items)
    {
        if (menuItem.Text == menuItemText){
            menuItem.Visible = true;
            break;  
        }      
    }
}

:)
