将char []转换为System :: String ^ [英] Convert char[] to System::String^

问题描述

如何将字符转换为System :: String ^?

我有这个:

How do i convert a char to a System::String^?

I have this:

System::String^ text;
 text = UART_WriteBuffer[UART_WriteIndexTail].ToString();

其中UART_WriteBuffer是char []，并且包含"at \ r". UART_WriteIndexTail的范围是0到2.

我希望文本在转换后包含"a"，但它包含以字符串形式表示的"a"的ASCII值"97".

where UART_WriteBuffer is a char[] and it contains "at\r". UART_WriteIndexTail ranges from 0 to 2.

I want text to contain "a" after the conversion but it contains "97" the ASCII value of "a" represented as a string.

推荐答案

简便的方法这是从字符数组创建String^并在字符串上使用索引器.

Easy way to do this is to create String^ from the character array and use the indexer on string.

String^ text = gcnew String(UART_WriteBuffer);

现在，您可以编写text[UART_WriteIndexTail].ToString()

如果需要单个字符，则可以

If you need a single character then you may do

System::String ^ text = gcnew String("");
str += (wchar_t) a[0];
