[英]System.IndexOutOfRangeException: Cannot find table 0.5
我在asmx中制作一個web方法，在其中我從不同的表中獲取數據...並填充數據集中的行..但是當我從不同的表中獲取數據時，如何填充我的數據集？ 請幫助我:(

我已經對您的代碼進行了一些重構，我想我已經為您提供了一個合理的解決方案。 嘗試這樣的事情來獲取數據：
var data =
from DataRow dr1 in dbo.getdata("SELECT Bcode,Bdesc FROM Gl_bSheet1 where Compcode='" + baranchcode + "'").Rows
let Bcode = (string)dr1[0]
select new
{
Bcode,
Bdesc = (string)dr1[1],
sheet2s =
from DataRow dr2 in dbo.getdata("SELECT Bncode,Bndesc FROM Gl_bSheet2 where Compcode='" + baranchcode + "' and Bcode='" + Bcode + "'").Rows
let Bncode = (string)dr2[0]
select new
{
Bncode,
Bndesc = (string)dr2[1],
sheet3s =
from DataRow dr3 in dbo.getdata("SELECT Bnicode,Bnidesc FROM Gl_bSheet3 where Compcode='" + baranchcode + "' and Bcode='" + Bcode + "' and Bncode='" + Bncode + "'").Rows
let Bnicode = (string)dr3[0]
select new
{
Bnicode,
Bnidesc = (string)dr3[1],
dataSheets =
from DataRow dr4 in dbo.getdata("SELECT gpls.Accountno,gd.Acct_Desc FROM Gl_bSheetdetail gpls,GL_Detail gd where gpls.Compcode='" + baranchcode + "' and gpls.Bcode='" + Bcode + "' and gpls.Bncode='" + Bncode + "' and gpls.Bnicode='" + Bnicode + "' and gpls.Accountno=gd.AccountNo").Rows
let Accountno = (string)dr4[0]
let finaldata = (string)(dbo.getdata("SELECT SUM(Dr_Amount)-SUM(Cr_Amount) from gl_transaction where Accountno='" + Accountno + "' and Value_Date between '" + fromdate + "' and '" + todate + "'").Rows[0].ItemArray[0])
where !String.IsNullOrEmpty(finaldata)
select new
{
Accountno,
Acct_Desc = (string)dr4[1],
value = decimal.Parse(finaldata)
}
}
}
};
然后使用以下代碼生成行：
foreach (var s1 in data)
{
var dd = ds.Tables[0].NewRow();
dd[0] = s1.Bdesc;
dd[1] = "sheet1";
dd[2] = "";
dd[3] = "";
ds.Tables[0].Rows.Add(dd);
foreach (var s2 in s1.sheet2s)
{
//Add Sheet2 Opening Row Here
foreach (var s3 in s2.sheet3s)
{
//Add Sheet3 Opening Row Here
//Add Data Row Here
var s3balance = s3.dataSheets
.Select(z => z.value)
.Sum();
//Add Sheet3 Closing Row Here
}
var s2balance = s2.sheet3s
.SelectMany(y => y.dataSheets)
.Select(z => z.value)
.Sum();
//Add Sheet2 Closing Row Here
}
var s1balance = s1.sheet2s
.SelectMany(x => x.sheet3s)
.SelectMany(y => y.dataSheets)
.Select(z => z.value)
.Sum();
//Add Sheet1 Closing Row Here
}
通常，最好使查詢遠離寫數據的代碼。 我認為這做得很好。
