c# - 将 C++ istringstream 用法转换为 C#

Question

我正在重写一些代码，想知道如何将其从 C++ 转换为 C#:

istringstream vertexString = new istringstream(s);

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

Answer 1

将其添加到静态字符串实用程序类:

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;
}

这样使用。 s 必须是字符串。

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