Code Inspection: Merge conditional ?: expression into conditional access
Starting from C# 6.0, you can use the null-conditional operator (?.) to test for null before performing a member access.
If you use the conditional ?: (ternary) operator for nullability check when accessing symbol's members, JetBrains Rider suggests to replace it with more elegant ?.
operator.
Here is an example of a quick-fix suggested by this inspection:
Suboptimal code | After the quick-fix |
---|---|
string GetAttr(XElement node, string attrName)
{
var attrNode = node.Attribute(attrName);
return attrNode == null ? null : attrNode.Value;
} |
string GetAttr(XElement node, string attrName)
{
var attrNode = node.Attribute(attrName);
return attrNode?.Value;
} |
