【问题描述】:
我想在我的 c# 程序中实现this 方法。但是我无法在一行中填写适当的参数,例如
long FirstRow = myWorksheet.Cells.Find(
What:="*",
After:=Range("IV65536"),
LookIn:=xlValues,
LookAt:= xlPart,
SearchOrder:=xlByRows,
SearchDirection:=xlNext).Row
Here is the documentation for the Range.Find method.
Range Find(
[In] object What,
[In, Optional] object After,
[In, Optional] object LookIn,
[In, Optional] object LookAt,
[In, Optional] object SearchOrder,
[In, Optional] XlSearchDirection SearchDirection,
[In, Optional] object MatchCase,
[In, Optional] object MatchByte,
[In, Optional] object SearchFormat
);
所以基本上我不知道如何制作合适的参数对象。
更新 Excel.Range范围;
object What = "*";
object After = xlWorkSheet.get_Range("A1", "IV65536");
object LookIn = "xlValues";
object LookAt = "xlPart";
object SearchOrder = "xlByRows";
Excel.XlSearchDirection SearchDirection = Excel.XlSearchDirection.xlNext;
object MatchCase = System.Reflection.Missing.Value;
object MatchByte = System.Reflection.Missing.Value;
object SearchFormat = System.Reflection.Missing.Value;
range = xlWorkSheet.Cells.Find(
What,
After,
LookIn,
LookAt,
SearchOrder,
SearchDirection,
MatchCase,
MatchByte,
SearchFormat
);
给出“未处理 COMException:类型不匹配。(来自 HRESULT 的异常:0x80020005 (DISP_E_TYPEMISMATCH))”
更新 #2 这是迄今为止的方法。唯一缺少的是设置和返回范围。
public void RealUsedRange()
{
int FirstRow = xlWorkSheet.Cells.Find(
"*",
xlWorkSheet.get_Range("IV65536", misValue),
Excel.XlFindLookIn.xlValues,
Excel.XlLookAt.xlPart,
Excel.XlSearchOrder.xlByRows,
Excel.XlSearchDirection.xlNext,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value
).Row;
int FirstColumn = xlWorkSheet.Cells.Find(
"*",
xlWorkSheet.get_Range("IV65536", misValue),
Excel.XlFindLookIn.xlValues,
Excel.XlLookAt.xlPart,
Excel.XlSearchOrder.xlByColumns,
Excel.XlSearchDirection.xlNext,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value
).Column;
int LastRow = xlWorkSheet.Cells.Find(
"*",
xlWorkSheet.get_Range("IV65536", misValue),
Excel.XlFindLookIn.xlValues,
Excel.XlLookAt.xlPart,
Excel.XlSearchOrder.xlByRows,
Excel.XlSearchDirection.xlPrevious,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value
).Row;
int LastColumn = xlWorkSheet.Cells.Find(
"*",
xlWorkSheet.get_Range("IV65536", misValue),
Excel.XlFindLookIn.xlValues,
Excel.XlLookAt.xlPart,
Excel.XlSearchOrder.xlByColumns,
Excel.XlSearchDirection.xlPrevious,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value
).Column;
}
【问题讨论】:
-
您使用的是Framework 4.0吗?您使用您的语法时遇到了哪种错误?
-
我正在使用框架 3.5。如果这就是您所指的,我知道 4.0 中的 dynamic type system。目前我没有收到任何错误,因为我不知道要执行的完整行。对于那些不使用的参数,当然应该有一个 System.Reflection.Missing.Value 对象。
