请注意,该字符串是动态数据.
read last 3 characters from string [Initially asked question]
您可以使用 string.Substring 并给出起始索引,它将从给定的索引到结尾处获得子串.
myString.Substring(str.Length-3)
Retrieves a substring from this instance. The substring starts at a specified character position. 07001

Remove last 3 characters from string [Updated question]
要从字符串中删除最后三个字符,您可以使用 string.Substring(Int32, Int32) ,并将其起始索引0和结束索引缩小到字符串长度的三分之一.它会在最后三个字符之前得到子字符串.
myString = myString.Substring(0, str.Length-3);
String.Substring Method (Int32, Int32)
Retrieves a substring from this instance. The substring starts at a specified character position and has a specified length.
您还可以使用 String.Remove(Int32) 方法通过将起始索引作为长度-3传递来删除最后三个字符,它将从此点移除到字符串结尾.
myString = myString.Remove(myString.Length-3)
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
