如何將此C++函數轉換爲c＃？

Question

我試過使用在線轉換器，但它沒有解決。

C++函數如下。我希望它在C＃中是等效的。

//! Save the SURF features to file 
void saveSurf(char *filename, vector<Ipoint> &ipts) 
{ 
    ofstream outfile(filename); 

    // output descriptor length 
    outfile << "64\n"; 
    outfile << ipts.size() << "\n"; 

    // create output line as: scale x y des 
    for(unsigned int i=0; i < ipts.size(); i++) 
    { 
    outfile << ipts.at(i).scale << " "; 
    outfile << ipts.at(i).x << " "; 
    outfile << ipts.at(i).y << " "; 
    outfile << ipts.at(i).orientation << " "; 
    outfile << ipts.at(i).laplacian << " "; 
    outfile << ipts.at(i).scale << " "; 
    for(int j=0; j<64; j++) 
     outfile << ipts.at(i).descriptor[j] << " "; 

    outfile << "\n"; 
    } 

    outfile.close(); 
} 

我覺得ofstream是streamwriter或者可能是filestream。

Answer 1

使用TextWriter類。

using (StreamWriter writer = File.CreateText("file.txt")) 
{ 
    writer.WriteLine("64"); 
    // etc. 
} 

或者異步：

using (StreamWriter writer = File.CreateText("file.txt")) 
{ 
    await writer.WriteLineAsync("64"); 
    // etc. 
}
