String splitting () function parsing-C #

Today, a friend asked me, if the database field contains data "5, 6, 8, 9", how can I retrieve the values separately, data is extracted first and then Split in CSHARP. However, many friends may not know how to use the Split () function of the string class object function to Split data. Now we will mainly explain this Split. First, make a mark. Later, I will review my own blog posts and learn some knowledge to improve my basic knowledge.

This method of string objects is reloaded five times.

// Summary:
// Return the System. String Array containing the substring In the instance (separated by elements in the specified System. Char array.
//
// Parameters:
// Separator:
// An array of Unicode characters that separate the substring of this instance, an empty array that does not contain separators, or null.
//// Return result:
// An array whose elements contain substrings in this instance. These substrings are separated by one or more characters in the separator. For more information, see the remarks section.

Now, I am posting a piece of code to record it. I will not talk about anything else.

Protected void Page_Load (object sender, EventArgs e)
{
If (! IsPostBack)
{
String a = "5, 6, 9 ";
String [] B;
B = a. Split (',');
For (int I = 0; I <B. Length; I ++)
{
Response. Write (B [I]. ToString () + "</br> ");
}

}
}
