i want to replace the word STAR into BAT so the new output would be:
我想将单词 STAR 替换为 BAT，因此新输出将是：
TWINKLE TWINKLE LITTLE BAT FISH
is this possible? thanks in advance.

回答by Tim Schmelter
So you want to Replaceall occurences of one word with another?
所以你想把Replace一个词与另一个词的所有出现都放在一起？
sample = sample.Replace("STAR", "BAT")
If you want to ignore the case (.NET is case sensitive) you can use a regex:
如果您想忽略大小写（.NET 区分大小写），您可以使用正则表达式：
Dim regex = New Regex("STAR", RegexOptions.IgnoreCase)
sample = regex.Replace(sample, "BAT")
(remember to add Imports System.Text.RegularExpressions)
（记得加Imports System.Text.RegularExpressions）

Dim sample as string = "TWINKLE TWINKLE LITTLE STAR FISH"
if sample.contains("STAR") then
dim change_star as string
change_star = sample.replace("STAR","BAT")
messagebox.show("change_star")
'NOTE: output change_star
Endif
