如果我从aspx.cs文件中删除请求，这段代码可以工作但如果我包含它，它会给出这个错误，仍然在等待回复，我添加了检查条件，但仍然给我错误
这是我的类代码:using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Text.RegularExpressions;
namespace AQCConsolidator1
{
class MyClass1
{
string output;
string subs;
DataTable dt = new DataTable();
DataRow dr = null;
public DataTable GetNumber(List<string> request)
{
dt.Columns.Add("TickitNumber", typeof(string));
foreach (string data in request)
{
string item = data;
while (item.Trim() != "")
{
dr = dt.NewRow();
int r1 = item.IndexOf("'r",3);
subs = item.Substring(0, r1); ///Got error in this line
if (subs.Contains("ET"))
{
Regex regexs = new Regex(@"[0-9||-]{14}");
foreach (Match m in regexs.Matches(subs))
{
output = m.ToString();
dr["TickitNumber"] = output;
}
dt.Rows.Add(dr);
}
item = item.Substring(subs.Length);
r1 = item.IndexOf("'r'n", 0);
item = item.Substring(r1);
}
}
return dt;
}
}
}
int r1 = item.IndexOf("'r",3);
subs = item.Substring(0, r1); ///Got error in this line
IndexOf将返回-1作为索引。因此，您尝试在下一行从索引0调用SubString到索引-1。您应该添加一个检查，以确保在继续之前找到"'r"。
