    oldChar : char, 
    newChar : char, 
    startIndex : int,

) : StringBuilder

Parameters

• oldChar
  Type: System. . :: . .Char
  The character to replace.

• newChar
  Type: System. . :: . .Char
  The character that replaces oldChar.

• startIndex
  Type: System. . :: . .Int32
  The position in this instance where the substring begins.

• count
  Type: System. . :: . .Int32
  The length of the substring.

Return Value

Type: System.Text. . :: . .StringBuilder
A reference to this instance with oldChar replaced by newChar in the range from startIndex to startIndex + count -1.

Remarks

The size of the StringBuilder is unchanged because characters are only replaced. This method is case-sensitive.
