如果特定单元格使用C＃“ReadOnly”，如何使用DataReader在excel单元格中写入

I am using DataReader to write data into excelsheet cells. I have no problem until the cell has write previleges. But in one case, only one cell is readonly and the rest cells are writable.

我正在使用DataReader将数据写入excelsheet单元格。在单元格写入优先权之前我没有问题。但在一种情况下,只有一个单元是只读的,其余单元是可写的。

Eg : 10 * 10 cells, only first cell is readonly. so, i shuld leave this cell and write it to rest of the cells. But with the data reader it writes entire row at one go.. so how can i acheive this using C# ?

例如:10 * 10个细胞,只有第一个细胞是只读的。所以,我shuld离开这个细胞并将其写入其余的细胞。但是使用数据读取器,它可以一次性写入整行......那么我如何使用C#实现这一目标呢?

so, the first cell shouldn't be written by datareader. Please help me in doing this

所以,第一个单元格不应该由datareader写入。请帮我这样做

if (reader.HasRows)
{
    minRow = 0;
    minCol = 0;
    // Process each result in the result set
    while (reader.Read())
    {
        // Create an array big enough to hold the column values
        object[] values = new object[reader.FieldCount];
        // Add the array to the ArrayList
        rowList.Add(values);
        // Get the column values into the array
        reader.GetValues(values);
        int iValueIndex = 0;

        // If the Reading Format is by ColumnByColumn 
        if (CurTaskNode.ReadFormat == "ColumnbyColumn")
        {
            minCol = 0;
            //   minRow = 0;
            for (int iCol = 0; iCol < CurTaskNode.HeaderData.Length; iCol++)
            {
                // Checking whether the Header data exists or not
                if (CurTaskNode.HeaderData[minCol] != "")
                {
                    // Assigning the Value from reader to the particular cell in excel sheet                   
                    excelworksheet.Cells[CurTaskNode.DATA_MIN_ROW + minRow, CurTaskNode.DATA_MIN_COL + minCol] = values[iValueIndex];
                    iValueIndex++;
                }
                minCol++;
            }
            minRow++;
        }
    }
}

Thank you, Ramm

Found this on google so maybe it works/maybe it doesn't: here, code looks the same as yours

在谷歌上找到这个可能它的工作/也许它没有:在这里,代码看起来与你的相同

You can use the AllowEdit property of a range so you could do:

您可以使用范围的AllowEdit属性,以便执行以下操作:

// Assigning the Value from reader to the particular cell in excel sheet      
Excel.Range c = (Excel.Range)excelworksheet.Cells[CurTaskNode.DATA_MIN_ROW + minRow, CurTaskNode.DATA_MIN_COL + minCol];
if (c.AllowEdit) c.Value2 = values[iValueIndex];

instead of

// Assigning the Value from reader to the particular cell in excel sheet                   
excelworksheet.Cells[CurTaskNode.DATA_MIN_ROW + minRow, CurTaskNode.DATA_MIN_COL + minCol] = values[iValueIndex];

I tried a lot to figure out how to skip writin onto a particular excel cell using C#, but couldnt get the proper logic.

我试了很多想弄清楚如何使用C#跳过写入特定excel单元格,但无法获得正确的逻辑。

my eg: Team Leader (required) abcxyz User1 user2 Customer Interface Focal dfgidf user23 user3

我的eg:团队负责人(必填)abcxyz User1 user2客户界面焦点dfgidf user23 user3

each of the names above has to be in a particular cell... but in the excel template, first cell (Team Leader (required)) is readonly, so i cant write into that cell, so my final excel sheet should show

上面的每个名称都必须在特定的单元格中...但在excel模板中,第一个单元格(团队负责人(必填))是只读的,所以我不能写入该单元格,所以我的最终excel表格应该显示

                            abcxyz  User1   user2
Customer Interface Focal    dfgidf  user23  user3.....
.....

i tried various logics for this... please see the code below

我为此尝试了各种逻辑...请参阅下面的代码

Microsoft.Office.Interop.Excel.Workbook SelWorkBook = excelappln1.Workbooks.Open(
    curfile,
    0, false, 5, "", "", false,
    Microsoft.Office.Interop.Excel.XlPlatform.xlWindows,
    "", true,
    false, 0, false, false, false);

Microsoft.Office.Interop.Excel.Sheets excelSheets = SelWorkBook.Worksheets;
Microsoft.Office.Interop.Excel.Worksheet excelworksheet =(Microsoft.Office.Interop.Excel.Worksheet)excelSheets.get_Item(CurSheetName);

Microsoft.Office.Interop.Excel.Range excelRange = excelworksheet.UsedRange;

if ((!excelworksheet.Cells[CurTaskNode.DATA_MIN_ROW + minRow, CurTaskNode.DATA_MIN_COL + minCol]).Locked)
{
    // Assigning the Value from reader to the particular cell in excel sheet 
    excelworksheet.Cells[CurTaskNode.DATA_MIN_ROW + minRow, CurTaskNode.DATA_MIN_COL +      minCol] = values[iValueIndex];
    iValueIndex++;
}

but the error shows, in the if statement Error 1 Operator '!' cannot be applied to operand of type 'object'

但错误显示,在if语句错误1运算符'!'不能应用于'对象'类型的操作数

so, please say how to handle this case.

所以,请说明如何处理这个案子。

Thanks Ramm
