asp.net StringBuilder Usage Example code _ Practical Tips

To achieve this effect

Copy Code code as follows:

public static string Shownewmsg ()
{
String Pic1 = "Images/yzdp-_15.gif";
String Pic2 = "Images/yzdp-_18.gif";
String Pic3 = "Images/yzdp-_20.gif";
String Pic4 = "Images/yzdp-_22.gif";
String Pic5 = "Images/yzdp-_24.gif";
String Pic6 = "Images/yzdp-_26.gif";
String Pic7 = "Images/yzdp-_28.gif";
String Pic8 = "Images/yzdp-_30.gif";
String Pic9 = "Images/yzdp-_32.gif";
String Pic10 = "Images/yzdp-_34.gif";
