vc中常用的几个数据转换方法-int char* float与CString 之间的转换

1、int <->CString

1) int ->CString

int n = 1;

CString str;

str.Format("%d",n);

2) CString->int

CString str = "1";

int n = atoi(str.GetBuffer(0));

2. char* 与CString

1)char*->CString

char sz[128];

CString str;

str.Format("%s",sz);

2) CString -> char*

CString str;

int nLength = str.GetLength();

char* sz = new char[nLength];

sz = str.GetBuffer(0);

有人说这里有错误！会造成内存泄露；

char* sz = new char[nLength];

sz = str.GetBuffer(0);

应改为：

char* sz = str.GetBuffer(0);

3. float<->CString

1）float->CString

float f = 0.0;

CString str;

str.Format("%f",f);

2) CString->float

CString str = "0.0";

float f = atof(str.GetBuffer(0));
