C# Excel后期绑定entireclumn.NumberFormat

如何使用后期绑定设置Range.EntireColumn.NumberFormat？我目前拥有以下代码：

 object rg = ws.GetType().InvokeMember("Cells", BindingFlags.GetProperty, null, ws, new object[2]{1,iCol});
 object ec = rg.GetType().InvokeMember("EntireColumn", BindingFlags.GetProperty, null, rg, null);
 rg.GetType().InvokeMember("NumberFormat", BindingFlags.SetProperty, null, rg, new object[1] { "DD/MM/YYYY" });

对于AutoFit方法，我有以下内容：

object rng = ws.GetType().InvokeMember("UsedRange", BindingFlags.GetProperty, null, ws, null);
object cols = rng.GetType().InvokeMember("Columns", BindingFlags.GetProperty, null, rng, null);
cols.GetType().InvokeMember("AutoFit", BindingFlags.InvokeMethod, null, cols, null);

对于AutoFit，我不确定我是否做得很好。

经过了尝试和测试

private void button1_Click(object sender, EventArgs e)
{
    object xlApp;
    object xlWbCol;
    object xlWb;
    object xlSheet;
    object xlRange;
    object xlWsCol;

    //~~> create new Excel instance
    Type tp;
    tp = Type.GetTypeFromProgID("Excel.Application");
    xlApp = Activator.CreateInstance(tp);

    object[] parameter = new object[1];
    parameter[0] = true;
    xlApp.GetType().InvokeMember("Visible", BindingFlags.SetProperty, null, xlApp, parameter);
    xlApp.GetType().InvokeMember("UserControl", BindingFlags.SetProperty, null, xlApp, parameter);

    //~~> Get the xlWb collection
    xlWbCol = xlApp.GetType().InvokeMember("Workbooks", BindingFlags.GetProperty, null, xlApp, null);

    //~~> Create a new xlWb
    xlWb = xlWbCol.GetType().InvokeMember("Add", BindingFlags.InvokeMethod, null, xlWbCol, null);

    //~~> Get the worksheet collection
    xlWsCol = xlWb.GetType().InvokeMember("WorkSheets", BindingFlags.GetProperty, null, xlApp, null);

    //~~> Create a new workxlSheet
    xlSheet = xlWb.GetType().InvokeMember("Add", BindingFlags.InvokeMethod, null, xlWsCol, null);

    //~~> Assign cell to xlRange object
    xlRange = xlSheet.GetType().InvokeMember("Cells", BindingFlags.GetProperty, null, xlSheet, new object[2] { 1, 1 });

    //~~> Write a date to cell 
    xlRange.GetType().InvokeMember("Value", BindingFlags.SetProperty, null, xlRange, new object[] { "1-1-2012" });

    //~~> Get the column
    object cols = xlRange.GetType().InvokeMember("Columns", BindingFlags.GetProperty, null, xlRange, null);

    //~~> Autofit the column
    cols.GetType().InvokeMember("AutoFit", BindingFlags.InvokeMethod, null, cols, null);
    //~~> Format the entire Column
    cols.GetType().InvokeMember("NumberFormat", BindingFlags.SetProperty, null, cols, new object[1] { "DD/MM/YYYY" });

    //~~> Release the object
    //System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);
}

注意：使用System.Reflection添加

对于
usedrange
的自动调整，此功能有效

private void button1_Click(object sender, EventArgs e)
{
    object xlApp;
    object xlWbCol;
    object xlWb;
    object xlSheet;
    object xlRangeUsdRng;
    object xlRange;
    object xlWsCol;

    //~~> create new Excel instance
    Type tp;
    tp = Type.GetTypeFromProgID("Excel.Application");
    xlApp = Activator.CreateInstance(tp);

    object[] parameter = new object[1];
    parameter[0] = true;
    xlApp.GetType().InvokeMember("Visible", BindingFlags.SetProperty, null, xlApp, parameter);
    xlApp.GetType().InvokeMember("UserControl", BindingFlags.SetProperty, null, xlApp, parameter);

    //~~> Get the xlWb collection
    xlWbCol = xlApp.GetType().InvokeMember("Workbooks", BindingFlags.GetProperty, null, xlApp, null);

    //~~> Create a new xlWb
    xlWb = xlWbCol.GetType().InvokeMember("Add", BindingFlags.InvokeMethod, null, xlWbCol, null);

    //~~> Get the worksheet collection
    xlWsCol = xlWb.GetType().InvokeMember("WorkSheets", BindingFlags.GetProperty, null, xlApp, null);

    //~~> Create a new workxlSheet
    xlSheet = xlWb.GetType().InvokeMember("Add", BindingFlags.InvokeMethod, null, xlWsCol, null);

    //~~> Assign cell F5 to xlRange object for testing purpose
    xlRange = xlSheet.GetType().InvokeMember("Cells", BindingFlags.GetProperty, null, xlSheet, new object[2] {5, 6 });
    xlRange.GetType().InvokeMember("Value", BindingFlags.SetProperty, null, xlRange, new object[] { "1-1-2012" });

    //~~> Assign UsedRange
    xlRangeUsdRng = xlSheet.GetType().InvokeMember("UsedRange", BindingFlags.GetProperty, null, xlSheet, null);

    //~~> Get the Columns
    object cols = xlRangeUsdRng.GetType().InvokeMember("EntireColumn", BindingFlags.GetProperty, null, xlRangeUsdRng, null);

    //~~> Autofit
    cols.GetType().InvokeMember("AutoFit", BindingFlags.InvokeMethod, null, cols, null);

}

嗨，赛伦，欢迎来到SO！我来自VBA世界，不是c#，所以这可能不起作用，但还是试试吧。如果
ws
或
rg
被定义为对象，但实际上是一个工作表或范围对象，则可以使用与早期绑定相同的方法访问它们的方法/属性。因此，请尝试，
ws.Cells（…）
！你的autofit代码也适用于我…Hi Siddharth-谢谢你的回答，我现在就试试，我的问题是代码不起作用，它没有做它应该做的事情，但是看看你的代码，我想我误解了使用latebinding，我想这是因为这是我第一次使用它，但是谢谢：）找到了数字格式的解决方案，只是使用你之前发布的代码，所以你现在可以返回它，我只是在每个单元格中循环，然后一个接一个地设置它们的格式，剩下的只有autoFit感谢@SiddharthRout！！请参阅后续内容。在下面关于
