在Xrad Studio中将unicodestring转换为字符串 [英] convert unicodestring to string in xrad studio

问题描述

我在 Rad Studio 10 Seattle中遇到问题，我试图从 TEdit 对象获取文本输入，并且收到一条错误消息，说

I have a problem in "Rad Studio 10 Seattle" where I am trying to get text input from a TEdit object and I get a errormessage saying

E2034无法将'UnicodeString'转换为'string'

E2034 Cannot convert 'UnicodeString' to 'string'

我的代码如下：

this->shopVar->addDog(edName->Text, StrToInt(edAge->Text), "male", "dogspecial");

此功能 addDog 需要（字符串，整数，字符串，字符串）

当我尝试从 TEdit 对象发送文本时， edName->文本我收到了前面提到的错误消息。

This function addDog takes (string, int, string, string)
When I try to send the text from the TEdit object with edName->Text I get the errormessage mentioned earlier.

我的问题如下，我可以在 edName 上从unicodestring转换为string还是我必须更改我的参数列表的数据类型？如果是这样，该怎么办？

我一直在搜索此问题，但未发现与我的问题类似的任何东西。

My question is as follows, can i make a convertion on edName from unicodestring to string or do I have to change the datatype of my parameterlist? If so, how do I do it?
I have been searching for this issue but have not found anything that is similar to my problem.

推荐答案

您需要先将 UnicodeString 数据转换为Ansi，然后将其传递。最简单的方法是先将 UnicodeString 分配给 AnsiString （或派生），然后使用其 c_str（）方法获取 char * 指针，该指针 std :: string 将接受：

You need to convert the UnicodeString data to Ansi first, then pass that instead. The easiest way is to assign the UnicodeString to an AnsiString (or derivative) first, and then use its c_str() method to get a char* pointer, which std::string will accept:

this->shopVar->addDog(AnsiString(edName->Text).c_str(), ...);

如果可能，也许考虑重写您的 shopVar 类使用 std :: wstring 代替，则可以删除Ansi转换：

If possible, maybe consider rewriting your shopVar class to use std::wstring instead, then you can remove the Ansi conversion:

this->shopVar->addDog(edName->Text.c_str(), StrToInt(edAge->Text), L"male", L"dogspecial");
