调用参数过多的方法-新手(可能) [英] Calling a method with too many parameters - Newbie (probably)

问题描述

如何正确书写??

它说了很多论点，所以我要怎么写而没有错误呢??

how to write that correctly???

It says to many arguments so how am I going to write that without error???

For i As Integer = 1 To 10 Step 1
          cboCategoryName.Items.Add(frmSuppliers.txtFName.Text, frmSuppliers.txtMName.Text, frmSuppliers.txtLName.Text)
      Next

然后，它说设置DataSource属性时不能修改Items集合.

我为此使用绑定，但是当我绑定它时，我只能在3个文本框中显示一个文本，如何使它显示3个文本.

It then says that Items collection cannot be modified when the DataSource property is set.

I use binding for this but when I bind it I could only display one text among the 3 textboxes how am I going to make it display the 3 text.

推荐答案

使用VS intellisense知道需要在其中添加哪些参数(类型和数字).

看起来像这样:

Use VS intellisense to know what paramters (type and number) needs to be added there.

Looks like, this might fit:

For i As Integer = 1 To 10 Step 1
   cboCategoryName.Items.Add(frmSuppliers.txtFName.Text &  frmSuppliers.txtMName.Text & frmSuppliers.txtLName.Text)      
Next

这对您来说并不是一个好主意.您的主题行应具有足够的描述性，以表明您要查找的内容.

应该是

This is not really a good subject line for you. Your subject line should be descriptive enough to indicate what you are looking for.

It should be

For i As Integer = 1 To 10
    cboCategoryName.Items.Add(String.Format("{0} {1} {2}, frmSuppliers.txtFName.Text, frmSuppliers.txtMName.Text, frmSuppliers.txtLName.Text)
   Next

项目集合有1个参数.如果要在其项目集合中添加一个句子，则需要进行合并.

Item collection takes 1 argument. If you are going to add a sentence to its item collection, you need to concat.
