所以我的程序应该正常工作。单击“保存”按钮时，所有内容都将保存到数据库中。但是，当我第二次单击保存按钮时，它无法工作。索引超出了数组的范围。是私有空的错误btnTest_click在行字符串Ullage = splitstring [2];
private void btnSave_Click(object sender, EventArgs e)
{
OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\2014-06-26 TEK687 Config Tool\TEK687 Config Tool\bin\Debug\Results.mdb");
string SqlString = "insert into Table1 (PassOrFail,DateTested,TekNum,BatchNum,WeekNum,Serial,FirmwareVer,HardwareVer,TestPC,SettingsTest,Deleted,Ullage,SRC,Vbatt,Tamb,Ullage2,SRC2,Vbatt2,Tamb2) Values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";
using (OleDbCommand cmd = new OleDbCommand(SqlString, conn))
{
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("PassOrFail", txtPassFail.Text);
cmd.Parameters.AddWithValue("DateTested", txtDateTested.Text);

conn.Open();
cmd.ExecuteNonQuery();

您的splitstrings对象中没有三个对象，因此您无法访问索引2处的对象。因此，您应该在访问之前执行检查以确保它包含该索引处的对象，然后处理不合适的情况。
顺便说一句，下次你问一个关于为什么某些东西不起作用的问题时，你告诉我们你得到的异常绝对是至关重要的，而不是让我们要求它。并且您需要包含引发异常的代码。请参阅How to create a Minimal, Complete, and Verifiable example。

检查来自WriteTextAndWaitForResponse调用的变量。它可能没有3个逗号。
