    text
    copied!<p>At the moment my code successfully sets the value of fields/properties/arrays of an object using reflection given a path to the field/property from the root object.</p> <p>e.g.</p> <pre><code>//MyObject.MySubProperty.MyProperty SetValue('MySubProperty/MyProperty', 'new value', MyObject); </code></pre> <p>The above example would set 'MyProperty' property of the 'MyObject' object to 'new value'</p> <p>I'm unable to use reflection to set a value of a field in a struct which is part of an array of structs because the struct is a value type (within an array).</p> <p>Here are some test classes/structs...</p> <pre><code>public class MyClass { public MyStruct[] myStructArray = new MyStruct[] { new MyStruct() { myField = "change my value" } }; public MyStruct[] myOtherStructArray = new MyStruct[] { new MyStruct() { myOtherField = "change my value" }, new MyStruct() { myOtherField = "change my other value" } }; } public struct MyStruct { public string myField; public string myOtherField; } </code></pre> <p>Below is how I successfully set the value of normal properties/fields and props/fields in lists...</p> <pre><code>public void SetValue(string pathToData, object newValue, object rootObject) { object foundObject = rootObject; foreach (string element in pathToData.Split("/")) { foundObject = //If element is [Blah] then get the //object at the specified list position //OR foundObject = //Else get the field/property } //Once found, set the value (this is the bit that doesn't work for // fields/properties in structs in arrays) FieldInf.SetValue(foundObject, newValue); } object myObject = new MyClass(); SetValue("/myStructArray/[0]/myField", "my new value", myObject); SetValue("/myOtherStructArray/[1]/myOtherField", "my new value", myObject); </code></pre> <p>After that I want the myObject.myStructArray[0].myField = ''my new value" and myObject.myOtherStructArray[1].myOtherField = ''my new value"</p> <p>All I need is a replacement for the 'FieldInf.SetValue(foundObject, newValue);' line</p> <p>thanks in advance</p>
