Small Function VB.Net & C#

VB             C#

UBound()     = yourArray.GetUpperBound(0) or yourArray.Length for one-dimesional arrays
LBound()     = yourArray.GetLowerBound(0)
IsNothing()  = Object.ReferenceEquals(obj,null)
Chr()        = Convert.ToChar()
Len()        = "string".Length
UCase()      = "string".ToUpper()
LCase()      = "string".ToLower()
Left()       = "string".Substring(0, length)
Right()      = "string".Substring("string".Length - desiredLength)
RTrim()      = "string".TrimEnd()
LTrim()      = "string".TrimStart()
Trim()       = "string".Trim()
Mid()        = "string".Substring(start, length)
Replace()    = "string".Replace()
Split()      = "string".Split()
Join()       = String.Join()
MsgBox()     = MessageBox.Show()
IIF()        = (boolean_condition ? "true" : "false")

UBound()  — arrayVar.Length
LBound()  — obsolete, lower bound is always 0 in a normal .Net array
IsNothing()  — obsolete. Use Is Nothing in VB.Net and == null in C#
Chr() — Convert.ToChar() or (char)someVar
Len()  — stringVar.Length use this in VB too
UCase() — stringVar.ToUpper() use this in VB too
LCase() — stringVar.ToLower() use this in VB too
Left() — stringVar.Substring(0, n) use this in VB too
Right() — stringVar.Substring(stringVar.Length - n) use this in VB too
RTrim() — stringVar.TrimEnd() use this in VB too
LTrim() — stringVar.TrimStart() use this in VB too
Trim() — stringVar.Trim() use this in VB too
Mid() — stringVar.Substring(n, m) use this in VB too
Replace() — stringVar.Replace() use this in VB too
Split() — stringVar.Split() use this in VB too
Join() — String.Join() use this in VB too
MsgBox() — MessageBox.Show()
IIF() — (condition) ? truepart : falsepart - note that there are some differences, because "?" is an operator and not a function
