轉換C++ istringstream使用到C＃

Question

我重寫一些代碼，想知道怎樣才能從C++將其轉換爲C＃：

istringstream vertexString = new istringstream(s); 

//number of vertices 
int numVertices; 
vertexString>>numVertices; 

Answer 1

一下添加到一個靜態字符串的工具類：

public static Stream ToStream(this string str) 
{ 
    MemoryStream stream = new MemoryStream(); 
    StreamWriter writer = new StreamWriter(stream); 
    writer.Write(str); 
    writer.Flush(); 
    stream.Position = 0; 
    return stream; 
} 

使用喜歡這個。 s必須是字符串。

int numVertices; 
using (var stringStream = s.ToStream()) 
{ 
    stringStream>>numVertices; 
}
