String.Remove Method (Int32)
Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted.
Assembly: mscorlib (in mscorlib.dll)
startIndex is less than zero.
startIndex specifies a position that is not within this string.
In the .NET Framework, strings are zero-based. The value of the startIndex parameter can range from zero to one less than the length of the string instance.
This method does not modify the value of the current instance. Instead, it returns a new string in which all characters from position startIndex to the end of the original string have been removed.
The following example demonstrates the Remove method. The next-to-last case removes all text starting from the specified index through the end of the string. The last case removes three characters starting from the specified index.
