如何在C＃中将char转换为字符串

Question

我想将char转换为字符串，我该怎么办？

char[] buf;
Int32 dwsize;
buf = new char[256];
dwsize = 256;
if (Pxx_ATE.GetProjectName(DeviceId, decimal.ToInt32(up_ProIndex.Value), buf, dwsize))
{
  textBox_projName.Text = buf; //Here error,I want convert buf to string
}

Answer 1

替换

textBox_projName.Text = buf;

与

textBox_projName.Text = new string(buf);
