Invoke(string, params object[])

Invokes an instance method on the underlying JVM object using a variable-length argument list. The bridge resolves the target Java method by matching the runtime types of the supplied arguments.

object Invoke(string methodName, params object[] args)

Parameters

methodName string: The name of the Java instance method to invoke.
args object[]: The arguments to pass to the method. Each element must be a type compatible with the corresponding Java parameter: primitive types, IJavaObject instances, or .NET arrays of primitive types.

Returns

object: The return value of the method as a boxed object, or null if the method returns void.

Remarks

Use this overload when the number of arguments is not known at compile time. For a fixed, known number of arguments (0–10), prefer the strongly-typed overloads to avoid the overhead of array allocation.

Exceptions

MissingMethodException: Thrown if no method matching methodName with the inferred signature is found.

InvokeWithSignature(string, string)

Invokes an instance method on the underlying JVM object using an explicit JNI signature and no arguments.

Returns

Use this overload when method overload resolution by argument types alone is ambiguous, or when you want to pin the call to a specific Java method descriptor. The JNI signature format follows the standard Java descriptor notation, e.g. "()V" for a void method with no parameters.

Parameters

methodName string: The name of the Java instance method to invoke.

The explicit signature is resolved at the JNI level before dispatching the call, so this overload is suitable when multiple Java overloads share the same name and the bridge cannot unambiguously select the right one from the argument types alone. For a fixed, known number of arguments (0–10), prefer the strongly-typed overloads to avoid the overhead of array allocation.
