通过实例学习Virtools脚本语言VSL - 从数组读取字符串

<p>该系统演示了怎样用VSL从数组读取字符串，它是习题4的逆过程。</p>
<ol>
<li>开始，创建一个数组，进入"Array Setup"面板对它进行编辑。<br>
根据你的喜欢穿件一些列(Column)，并创建几行。<br>
现在再在每个单元格中填充一些文本。
</li>
<li> 你的数组可能会像下面这个样子：<br><br><div>
<div style="display: block; text-align: left;">
<a href="https://sites.google.com/site/x3dofcn/vsl-virtools/Examples/6_stringarray/example6.jpg?attredirects=0"><img src="https://sites.google.com/site/x3dofcn/_/rsrc/1245510842861/vsl-virtools/Examples/6_stringarray/example6.jpg" border="0" alt=""></a>
</div>
</div>
</li>
<li>在层级(Level)下创建一个脚本，并添加一个Run VSL BB。在VSL Script Manager工作区中，为该BB添加一个名为的"myarray"的pIn参数，类型为"Array"。编辑该参数，并将它设置给你的数组。<br><pre>void main()<br>
{<br><span>// Array where we will put the strings that will be read.</span>
<br>
ArrayString arrayString;<br><br><span>// String as temporary buffer.</span>
<br>
String tmp;<br><br><span>// Loop to read each array's cell.</span>
<br>
for (int c = 0; c &lt; myarray.GetColumnCount(); ++c) {<br>
for (int r = 0; r &lt; myarray.GetRowCount(); ++r) { <br><br><span>// First we get the size of the string at pos (r, c)<br>
// (zero included)</span>
<br>
int lengthToRead = myarray.GetElementStringValue(r, c, null);<br><br><span>// Then we resize the string before reading the array.<br></span>
tmp.Resize(lengthToRead-1);<br><br><span>// At last, we can read the string.<br>
// Note that 3rd parameter of GetElementStringValue is a str<br>
// and not an String. </span>
<br>
myarray.GetElementStringValue(r, c, tmp.Str());<br><br><span>// We keep the read string in our array.</span>
<br>
arrayString.PushBack(tmp);<br>
}<br>
}<br><br><span>// We can do what we want with these strings.</span>
<br>
int stringNb = arrayString.Size();<br>
for (int i = 0; i &lt; stringNb; ++i) {<br>
bc.OutputToConsole(arrayString[i].Str());<br>
}<br>
}<br></pre>
</li>
</ol>
