[英]Split string by length to Excel
我目前正在發送長行數據並將其拆分到Excel。 每個拆分均在新行中打印。 我想將其從現有數據中的管道符號拆分為字符長度85拆分,但是,有可能在字符85中將一個單詞拆分為兩個。 如果要拆分實際單詞,我將如何告訴它進一步拆分為數據。 我知道如果在85歲以后也應該找到一個空格。 我很好奇要添加的內容。
// Add Description
string DescriptionSplit = srcAddOnPanel.Controls["txtProductDescAddOn" + AddRow].Text;
string[] descriptionParts = DescriptionSplit.Split('|');
int i;
for (i = 0; i <= descriptionParts.GetUpperBound(0); i++)
{
worksheet.Rows[currentRow].Insert(); //applies the description for the default bundle row
worksheet.Rows[currentRow].Font.Bold = false;
worksheet.Cells[currentRow, "E"].Value = rowIndent + descriptionParts[i].Trim();
currentRow++;
}
您可以使用這種方法(警告尚未完全測試)
int x = 85;
int y = 0;
int currentRow = 0;
// Loop until you have at least 85 char to grab
while (x + y < DescriptionSplit.Length)
{
// Find the first white space after the 85th char
while (x + y < DescriptionSplit.Length &&
!char.IsWhiteSpace(DescriptionSplit[x+y]))
x++;
// Grab the substring and pass it to Excel for the currentRow
InsertRowToExcel(DescriptionSplit.Substring(y, x), currentRow);
// Prepare variables for the next loop
currentRow++;
y = y + x + 1;
x = 85;
}
// Do not forget the last block
if(y < DescriptionSplit.Length)
InsertRowToExcel(DescriptionSplit.Substring(y), currentRow);
...
void InsertRowToExcel(string toInsert, int currentRow)
{
worksheet.Rows[currentRow].Insert();
worksheet.Rows[currentRow].Font.Bold = false;
worksheet.Cells[currentRow, "E"].Value = rowIndent + toInsert.Trim();
}
這是一個似乎可行的VBA版本。 正如我的評論中所建議的那樣,它用空格分隔字符串,然后測試添加單詞是否使當前行的長度大於最大值(85)。 像往常一樣,要使最后的單詞正確填充很難。
如果這對您有效,那么將其修改為C#應該足夠簡單。 讓我知道是否不正確:
Sub ParseRows()
Const ROW_LENGTH As Long = 85
Dim Text As String
Dim Words As Variant
Dim RowContent As String
Dim RowNum As Long
Dim i As Long
Text = ActiveCell.Text
Words = Split(Text, " ")
RowNum = 2
For i = LBound(Words) To UBound(Words)
If Len(RowContent & Words(i) & " ") > ROW_LENGTH Then
ActiveSheet.Range("A" & RowNum).Value = RowContent
RowNum = RowNum + 1
If i = UBound(Words) Then
RowContent = Words(i)
Else
RowContent = ""
End If
Else
RowContent = RowContent & Words(i) & " "
End If
Next i
If RowContent <> "" Then ActiveSheet.Range("A" & RowNum).Value = RowContent
End Sub
