Get a specific field of the current type C#
To get a specific field of the current type in C#, the code is as follows −
Example
using System;
using System.Reflection;
public class Demo {
public static void Main() {
Type type = typeof(Subject);
try {
FieldInfo fieldInfo = type.GetField("SubName");
Console.WriteLine("FieldInfo = {0}", fieldInfo);
}
catch (ArgumentNullException e) {
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
public class Subject {
public string SubName = "Science";
}Output
This will produce the following output −
FieldInfo = System.String SubName
Example
Let us see another example −
using System;
using System.Reflection;
public class Demo {
public static void Main() {
Type type = typeof(Subject);
try {
FieldInfo fieldInfo = type.GetField(null);
Console.WriteLine("FieldInfo = {0}", fieldInfo);
}
catch (ArgumentNullException e) {
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
public class Subject {
public string SubName = "Science";
}Output
This will produce the following output −
System.ArgumentNullException
