StringBuilder GetBefore

Demonstrates the StringBuilder.GetBefore method.

The GetBefore method was added in Chilkat v9.5.0.77

C#

bool success = false;

Chilkat.StringBuilder sb = new Chilkat.StringBuilder();
success = sb.Append("www.chilkatsoft.com");

//  The GetBefore method returns the contents of the string up to but not including
//  the marker string.  If the remove flag is true, then both the returned string AND
//  the marker are removed.
bool removeFlag = false;
string marker = ".";
string substr = sb.GetBefore(marker,removeFlag);
Debug.WriteLine("substr = " + substr);
Debug.WriteLine("sb contains: " + sb.GetAsString());

//  Output:
//  substr = www
//  sb contains: www.chilkatsoft.com

removeFlag = true;
substr = sb.GetBefore(marker,removeFlag);
Debug.WriteLine("substr = " + substr);
Debug.WriteLine("sb contains: " + sb.GetAsString());

//  Output:
//  substr = www
//  sb contains: chilkatsoft.com

//  If the marker is not found, and the removeFlag is true,
//  then the entire string is returned and the sb is cleared.
//  For example:
sb.Clear();
sb.Append("111--222--333--444");
marker = "--";
removeFlag = true;
while ((sb.Length > 0)) {
    substr = sb.GetBefore(marker,removeFlag);
    Debug.WriteLine("substr = " + substr + ", sb contains: " + sb.GetAsString());
}

//  Output is:
//  substr = 111, sb contains: 222--333--444
//  substr = 222, sb contains: 333--444
//  substr = 333, sb contains: 444
//  substr = 444, sb contains:
