    copied!<p>I am attempting to learn SharpDX via DirectX tutorials. I have this line of code in the C++ project I am working from:</p> <pre><code>std::ifstream fin("Models/skull.txt"); if(!fin) { MessageBox(0, L"Models/skull.txt not found.", 0, 0); return; } UINT vcount = 0; UINT tcount = 0; std::string ignore; fin &gt;&gt; ignore &gt;&gt; vcount; fin &gt;&gt; ignore &gt;&gt; tcount; fin &gt;&gt; ignore &gt;&gt; ignore &gt;&gt; ignore &gt;&gt; ignore; float nx, ny, nz; XMFLOAT4 black(0.0f, 0.0f, 0.0f, 1.0f); std::vector&lt;Vertex&gt; vertices(vcount); for(UINT i = 0; i &lt; vcount; ++i) { fin &gt;&gt; vertices[i].Pos.x &gt;&gt; vertices[i].Pos.y &gt;&gt; vertices[i].Pos.z; vertices[i].Color = black; // Normal not used in this demo. fin &gt;&gt; nx &gt;&gt; ny &gt;&gt; nz; } fin &gt;&gt; ignore; fin &gt;&gt; ignore; fin &gt;&gt; ignore; mSkullIndexCount = 3*tcount; std::vector&lt;UINT&gt; indices(mSkullIndexCount); for(UINT i = 0; i &lt; tcount; ++i) { fin &gt;&gt; indices[i*3+0] &gt;&gt; indices[i*3+1] &gt;&gt; indices[i*3+2]; } fin.close(); </code></pre> <p>And I would like to know how to covert this over to C#. I am 99% sure I need to be using <code>System.IO.FileStream</code> but I am unsure how all the C++ stuff works. What is really messing me up is the <code>fin &gt;&gt; ignore &gt;&gt; vcount;</code> If someone can explain to me how to do the same thing in C# I can probably figure it out from there.</p> <p>As requested the text file resembles this:</p> <pre><code>VertexCount: 31076 TriangleCount: 60339 VertexList (pos, normal) { 0.592978 1.92413 -2.62486 0.572276 0.816877 0.0721907 0.571224 1.94331 -2.66948 0.572276 0.816877 0.0721907 0.609047 1.90942 -2.58578 0.572276 0.816877 0.0721907 … } TriangleList { 0 1 2 3 4 5 6 7 8 … } </code></pre>
