* 强文 我有一个richTextBox,喜欢搜索以Hello Worlds开头并包含“HERE”的句子行。结束;我想删除半列 “HERE”。 。我的句子,下面的例子只是一行句子,但句子可能是2行长,所以条件应该从Hello Worlds开始并以;半列除了删除 “HERE”。*
我的一句话:
Hello Worlds the weather is too hot "HERE"."IN" CANADA!;
我的2行句子可能就是这样:
Hello Worlds the weather is too hot "HERE"."IN" CANADA!. But we are still like it;
结果应为一行:
Hello Worlds the weather is too hot "IN" CANADA!;
结果应为2行:
Hello Worlds the weather is too hot "IN" CANADA!. But we are still like it;
我坚持使用我的代码:
List<string> rt = new List<string>();
foreach (string line in richTextBox1.Lines)
{
if (line.StartsWith("Hello Worlds") && line.Contains("HERE"))
{
//remove "HERE".
}
}
答案 0 :(得分:1)
你可以这样做
string[] lines = richTextBox1.Lines;
List<string> linesToAdd = new List<string>();
string filterString = "\"HERE\".";
foreach (string s in lines)
{
string temp = s;
if (s.StartsWith("Hello Worlds") && s.EndsWith(";") && s.Contains(filterString))
temp = s.Replace(filterString, string.Empty);
linesToAdd.Add(temp);
}
richTextBox1.Lines = linesToAdd.ToArray();
