您应该处理SqlConnection，以防止内存泄漏和未关闭的连接。“using”关键字负责调用“finally”，从而关闭您的连接：
public List<TransactionIssues> GetAllTransactions()
{
using(var connection = new SqlConnection(connectionString))
{
using(var command = new SqlCommand())
{
List<TransactionIssues> transIssues = new List<TransactionIssues>();
command.CommandText = "issue_sp_getallunpostedissues";
command.CommandType = CommandType.StoredProcedure;
command.Connection = connection;
connection.Open();
using(SqlDataReader rdrObj = command.ExecuteReader())
{
while (rdrObj.Read())
{
TransactionIssues issues = new TransactionIssues();
issues.requisitionNumber = rdrObj.GetString(0);
issues.transactionDate = rdrObj.GetDateTime(1);
//issues.expense_acccount.account_desc = rdrObj.GetString(2);
//issues.expense_acccount.index = rdrObj.GetInt16(3);
issues.inventory_acccount.index = rdrObj.GetInt32(2);
issues.inventory_acccount.account_desc = rdrObj.GetString(3);
issues.docNumber = rdrObj.GetString(4);
issues.docType = rdrObj.GetString(5);
issues.items = getTransItemByRquisition(rdrObj.GetString(4));
transIssues.Add(issues);
}
}
rdrObj.Close();
return transIssues;
}
}
}
如果您在使用命令后处置了该命令（例如，将其放入
usingrdrObj
