Create a text file and use different codes to generate garbled characters.

There is a program in the past two days. I need to dynamically create several text files.

I usually use
System. Io. streamwriter m_sw;

M_sw = system. Io. file. createtext (m_workfilename );

Create a text document. After the document is created, I add the content in another file.

The result is garbled.

I read the article and summarized the following points:

1. All text files must be encoded,

For example, system. Io. file. createtext is encoded in UTF-8.

2. We can use system. Text. coding. getencoding (INT codeint) to obtain the encoding information.

3. Pass
M_encoding = system. Text. encoding. getencoding (54936 );

M_sw = new streamwriter

(This. m_workfilename, false, m_encoding );

We can create a specified encoded file.
