内蒙古的菜鸟求高手解决下问题
代码功能是从excel中读数据：代码如下
for (int j = 1; j < 32; j++)
{

string path = @"D:\预警、重要报告、通报\乡镇\1\" + j + ".xls";
MessageBox.Show(path);
Microsoft.Office.Interop.Excel.Application excel2 = new Microsoft.Office.Interop.Excel.Application();
excel2.Visible = true; //得到WorkBook对象, 可以用两种方式之一: 下面的是打开已有的文件
Excel.Workbook xBook = excel2.Workbooks._Open(path, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); //xBook=xApp.Workbooks.Add(Missing.Value);//新建文件的代码
Excel.Sheets objSheets;
Excel._Worksheet objSheet;
Excel.Range range;//=new Range[100];
string[] td1 = new string[10000];
string[] td2 = new string[10000];
string[] tg1 = new string[10000];
string[] tg2 = new string[10000];
string[] qq1 = new string[10000];
string[] qq2 = new string[10000];



//Get a reference to the first sheet of the workbook.

objSheets = excel2.Worksheets;
objSheet = (Excel._Worksheet)objSheets.get_Item(1);
//Get a range of data.
range = objSheet.get_Range("A1", "M17");
object[,] saRet1 = (System.Object[,])range.get_Value(Missing.Value);

for (int i = 1; i < 18; i++)
{
td1[i] = Convert.ToString(saRet1[3, i]);
td1[i+17] = Convert.ToString(saRet1[10, i]);
tg1[i] = Convert.ToString(saRet1[5, i]);
tg1[i+17] = Convert.ToString(saRet1[12, i]);
qq1[i] = Convert.ToString(saRet1[2, i]);
qq1[i+17] = Convert.ToString(saRet1[9, i]);
}


Excel.Workbook workbook1 = excel2.Workbooks._Open(@"D:\预警、重要报告、通报\乡镇\JY.xls", Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value
, Missing.Value, Missing.Value, Missing.Value, Missing.Value);
Worksheet worksheet1 = (Worksheet)workbook1.Worksheets["Sheet1" ];

Worksheet worksheet2 = (Worksheet)workbook1.Worksheets["Sheetqy1"];
int tdd = 6,tgg=3;
for (int i1 = 1; i1 < 35;i1++ )
{


worksheet1.Cells[j + 1, tdd] = td1[i1];
worksheet1.Cells[j + 1, tgg] = tg1[i1];
worksheet2.Cells[j + 1, tdd] = qq1[i1];
excel2.Visible = true;
}
}
}
读的excel表如下（17行，13列）：
白脑包晴-22～-13狼　山晴-24～-14
新 华晴-22～-14城 关晴-23～-13

巴市机场晴-24～-14蛮会镇晴-22～-13
运行到： td1[i] = Convert.ToString(saRet1[3, i]);
出问题了，问题为：1、索引超出了数组界限
2、确保索引不是负数
3、确保数据列名称正确

[解决办法]
saRet1的大小是多少？i此时是多少？
