Replace()
OutputVar := instance.Replace(oldValue, newValue)
OutputVar := instance.Replace(oldValue, newValue, startIndex, count)
Replaces, within a substring of this instance, all occurrences of a specified string with another specified string.
oldValue
The string to replace.
Can be var number or string or any object that derives from MfObject.
newValue
The string that replaces oldValue, or null.
Can be var number or string or any object that derives from MfObject.
A reference to this instance with all instances of oldValue replaced by newValue.
Throws MfArgumentNullException if oldValue is null.
Throws MfArgumentException if The length of oldValue is zero.
Throws MfArgumentOutOfRangeException if enlarging the value of this instance would exceed MaxCapacity.
This method performs an ordinal, case-sensitive comparison to identify occurrences of oldValue in the specified substring. If newValue is null, all occurrences of oldValue are removed.
See Example below.
Replaces, within a substring of this instance, all occurrences of a specified string with another specified string.
oldValue
The string to replace.
Can be var number or string or any object that derives from MfObject.
newValue
The string that replaces oldValue, or null.
Can be var number or string or any object that derives from MfObject.
startIndex
The position in this instance where the substring begins.
Can be any type that matches IsInteger or var integer.
count
The length of the substring.
Can be any type that matches IsInteger or var integer.
A reference to this instance with all instances of oldValue replaced by newValue in the range from startIndex to startIndex + count - 1.
Throws MfArgumentNullException if oldValue is null.
Throws MfArgumentException if The length of oldValue is zero.
Throws MfArgumentOutOfRangeException if startIndex or count is less than zero.
- or -
startIndex plus count indicates a character position not within this instance.
- or -
Enlarging the value of this instance would exceed MaxCapacity.
This method performs an ordinal, case-sensitive comparison to identify occurrences of oldValue in the specified substring. If newValue is null, all occurrences of oldValue are removed.
