[HRData]
我需要从以下位置删除数据： Upper1 = 0 至 [HRDATA] 并将其存储在我的listbox1中，以便它不会显示在我的datagridview
中我尝试过使用topindex功能，但无济于事 我收到了错误
感谢帮助
答案 0 :(得分：2)
正如Alex所写，一个非常简单的代码是：
string[] lines = File.ReadLines("TextFile1.txt")
.SkipWhile(x => x != "Upper1=0")
.TakeWhile(x => x != "[HRData]")
.ToArray();
使用StreamReader它有点复杂（但不是那么多）
List<string> lines = new List<string>();
bool skipping = true;
using (var sr = new StreamReader("TextFile1.txt")) {
string line;
while ((line = sr.ReadLine()) != null) {
line = line.TrimEnd();
if (skipping) {
if (line == "Upper1=0") {
skipping = false;
}
}
if (!skipping) {
lines.Add(line);
if (line == "[HRData]") {
break;
}
}
}
}
现在由SkipWhile / TakeWhile完成之前的事情由标记skipping
（在这两种情况下，Upper1=0和[HRData]都在集合中获取）
这是StreamReader版本的一个小变体。它实现了一个非常简单的状态机（我知道，我很懒，我应该使用enum而不是int）来分割“之前”，“中间”之间的界限“和”之后“。
List<string> linesBefore = new List<string>();
List<string> lines = new List<string>();
List<string> linesAfter = new List<string>();
// 0 = before Upper1=0,
// 1 = between Upper1=0 and [HRData]
// 2 = after [HRData]
int state = 0;
using (var sr = new StreamReader("TextFile1.txt")) {
string line;
while ((line = sr.ReadLine()) != null) {
line = line.TrimEnd();
if (state == 0) {
if (line == "Upper1=0") {
state = 1;
lines.Add(line);
} else {
linesBefore.Add(line);
}
} else if (state == 1) {
lines.Add(line);
if (line == "[HRData]") {
state = 2;
}
} else {
// state == 2
linesAfter.Add(line);
}
}
}

这个例子
Regex.Replace(File.ReadAllText(@"C:\MyIniFile.txt"), // Read all lines into buffer.
@"(Upper1=0)(.*)(\[HRData\])", // Set upper to HRData to be removed
string.Empty, // 'replace' the section with a empty line
RegexOptions.Singleline)
.Split(new[] { "\r\n", "\r", "\n" }, // Split the remaining buffer into lines
StringSplitOptions.RemoveEmptyEntries); // Don't show empty lines.
