Clear()
Peek()
Pop()
Push()
CopyTo(array, offset) //copy to array

string.Compare(s1,s2); //case sensitive
string.Compare(s1,s2, true) //case not sensitive
string s3 = @"test \ .net"
string s6 string.Copy(s5);
string s7 = s6
S7 == S6
S7.Equals(s6)
string.Equals(s7,s6)
s7.Length
s3.EndWith("Test")
int offset = s3.indexOf("TEST") //first occurence
string s10 = s3.Insert(offset, "DDD");
string s11 = s3.Insert(s3.IndexOf("ddd"), "EEE");
s12.Split(delimiters)
Regex r = new Regex(" |,");
foreach( string s in r.Split(s12)) {}
StringBuilder
StringBuilder sb = new StringBuild();
Append()
