我已经开发了一个Windows服务来读取csv数据并将其写回数据库。执行程序后，它会正常工作，直到几分钟后达到以下行时触发错误。
cmd.ExecuteNonQuery();
错误的截图：
在这个错误出现之前，数据已被写入数据库。
触发错误需要2-3分钟的时间。
我将包含与此问题相关的代码块。
public void Insert()
{
if (this.OpenConnection() == true)
{
using(var reader = new StreamReader(@"C:\Users\Admin\source\Bargstedt.csv"))
{
List<string> listA = new List<string>();
while (!reader.EndOfStream)
{
var line = reader.ReadLine();
var values = line.Split(',');
string querynew = "INSERT INTO new_jobs"
+ "(job_reference,status,code,no1,no2,no3,dimension,date_assigned,root,variable,number,stable,constant)"
+ "VALUES (?jobNo, ?strClientName, ?strClientReference, ?strJobCategory, ?datCommisioned, ?datPromisedDelivery, ?division, ?date_assigned, ?root, ?variable, ?number, ?stable, ?constant)";
MySqlCommand cmd = connection.CreateCommand();
cmd.CommandText= querynew;
cmd.Parameters.Add("?jobNo", MySqlDbType.VarChar).Value = (values[0]);
cmd.Parameters.Add("?strClientName", MySqlDbType.VarChar).Value =(values[1]);
cmd.Parameters.Add("?strClientReference", MySqlDbType.VarChar).Value = values[2];
cmd.Parameters.Add("?strJobCategory", MySqlDbType.VarChar).Value = values[3];
cmd.Parameters.Add("?datCommisioned", MySqlDbType.VarChar).Value = values[4];
cmd.Parameters.Add("?datPromisedDelivery", MySqlDbType.VarChar).Value = values[5];
cmd.Parameters.Add("?division", MySqlDbType.VarChar).Value = values[7];
cmd.Parameters.Add("?date_assigned", MySqlDbType.VarChar).Value = values[9];
cmd.Parameters.Add("?root", MySqlDbType.VarChar).Value = values[10];
cmd.Parameters.Add("?variable", MySqlDbType.VarChar).Value = values[11];
cmd.Parameters.Add("?number", MySqlDbType.VarChar).Value = values[12];
cmd.Parameters.Add("?stable", MySqlDbType.VarChar).Value = values[13];
cmd.Parameters.Add("?constant", MySqlDbType.VarChar).Value = values[14];
cmd.ExecuteNonQuery(); **error line
}
}
this.CloseConnection();
}
}
为了更清楚，我会附上CSV文件和数据库结构的屏幕截图。
CSV文件中的某些行中间有空格，这就是为什么我在源代码中跳过第6行和第8行的原因。
