从vb到c#的代码转换 [英] code conversoin from vb to c#

问题描述

你好，
将一行代码c#转换为VB时出现错误
代码是
在vb:CType(MyUserControl.FindControl("txtid")，TextBox).Text =(CType(Val(mo.maxrows(从provider_master中选择max(supplier_id)max)))，整数)+ 1)

转换后，代码变为((TextBox)MyUserControl.FindControl("txtid")).Text =(Convert.ToInt32( Conversion .Val(mo.maxrows( 从Supplier_master中选择max(supplier_id)")))+ 1);
但问题是我在转换"附近遇到错误.指出Conversion不在当前上下文中.

Hello,
I am getting An error while converting a line of code c# to VB
the code is
in vb:CType(MyUserControl.FindControl("txtid"), TextBox).Text = (CType(Val(mo.maxrows("select max(supplier_id) from supplier_master")), Integer) + 1)


after conversion the code become like this ((TextBox)MyUserControl.FindControl("txtid")).Text = (Convert.ToInt32(Conversion.Val(mo.maxrows("select max(supplier_id) from supplier_master"))) + 1);
but the problem is that i am getting a error near Conversion. sating that Conversion is not in the current context.
will any one help me about this.

推荐答案

AFAIK，在C#中没有类似于Conversion的关键字.
您不需要执行任何其他操作(因为您已经使用过Convert.ToInt).

您也可以尝试使用Int32.TryParse [

AFAIK, there is no keyword like Conversion in C#.
You don''t need to do anything else (since you''ve already used Convert.ToInt).

You can also try using Int32.TryParse[^].

翻译不正确.必须是VisualBasic，Microsoft.VisualBasic.Conversion中的Conversion:
http://msdn.microsoft.com/zh-我们/library/microsoft.visualbasic.conversion%28v=vs.100%29.aspx [Parse或TryParse方法:
http://msdn.microsoft.com/en-us/library/system.int32. parse.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/f02979c7.aspx [ ^ ].

Bad translation. This must be Conversion from VisualBasic, Microsoft.VisualBasic.Conversion:
http://msdn.microsoft.com/en-us/library/microsoft.visualbasic.conversion%28v=vs.100%29.aspx[^].

You can always reference this assembly (Microsoft.VisualBasic.dll) and use it in C# project. But this is not a good thing, using a non-standard proprietary library. This must be "conversion" from string. The word "conversion" is pretty silly here, this is "parsing". A standard way of parsing from string is the Parse or TryParse methods:
http://msdn.microsoft.com/en-us/library/system.int32.parse.aspx[^],
http://msdn.microsoft.com/en-us/library/f02979c7.aspx[^].
