In .NET, you can't define structs within methods. You can either define them within a class or within a namespace, just not within a method.

Tried that, but it says &quot;a namespace can only contain types and namespace declarations&quot;.<br />
<br />
What now? :D<br />

<pre><code id="code-5929375">List&lt;ReductionData&gt; sArray = new List&lt;ReductionData&gt;();
			
		struct ReductionData {
			string reductionID;
			string reductionFS;
			string computedReduction;
		}
</code></pre>
</div>


<div>
Try this:<br />
<br />

<pre><code id="code-20-34458562-1">public void SaveLevelingData()
{
	List&lt;ReductionData&gt; sArray = new List&lt;ReductionData&gt;();
}

public class ReductionData {
	string reductionID;
	string reductionFS;
	string computedReduction;
}</code></pre>

Why can't I have this code?  It's saying the struct is an "unexpected symbol".   I have the same exact struct in another class. (this is part of a partial class).

In .NET, you can&#39;t define structs within methods. You can either define them within a class or within a namespace, just not within a method.

Struct in a method...

Why can&#39;t I have this code?  It&#39;s saying the struct is an &quot;unexpected symbol&quot;.   I have the same exact struct in another class. (this is part of a partial class).

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
